+# zlogspace
+
+> Fill a double-precision complex floating-point strided array with logarithmically spaced values over a specified interval.
+
+
+
+## Usage
+
+```javascript
+var zlogspace = require( '@stdlib/blas/ext/base/zlogspace' );
+```
+
+#### zlogspace( N, base, start, stop, endpoint, x, strideX )
+
+Fills a double-precision complex floating-point strided array with logarithmically spaced values over a specified interval.
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+
+var x = new Complex128Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+var strt = new Complex128( 0.0, 0.0 );
+var stp = new Complex128( 2.0, 0.0 );
+
+zlogspace( x.length, 10.0, strt, stp, true, x, 1 );
+// x => [ 1.0, 0.0, 10.0, 0.0, 100.0, 0.0 ]
+```
+
+The function has the following parameters:
+
+- **N**: number of indexed elements.
+- **base**: base of the logarithmic scale.
+- **start**: exponent of the starting value, where the starting value is given by `base^start`.
+- **stop**: exponent of the final value, where the final value is given by `base^stop`.
+- **endpoint**: boolean indicating whether to include the `base^stop` value when writing values to the input array. If `true`, the input array is filled with logarithmically spaced values over the closed interval `[base^start, base^stop]`. If `false`, the input array is filled with logarithmically spaced values over the half-open interval `[base^start, base^stop)`.
+- **x**: input [`Complex128Array`][@stdlib/array/complex128].
+- **strideX**: stride length.
+
+The `N` and stride parameters determine which elements in the strided array are accessed at runtime. For example, to fill every other element:
+
+
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+
+var x = new Complex128Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+var strt = new Complex128( 0.0, 0.0 );
+var stp = new Complex128( 3.0, 0.0 );
+
+zlogspace( 4, 10.0, strt, stp, true, x, 2 );
+// x => [ 1.0, 0.0, 0.0, 0.0, 10.0, 0.0, 0.0, 0.0, 100.0, 0.0, 0.0, 0.0, 1000.0, 0.0, 0.0, 0.0 ]
+```
+
+Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views.
+
+
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+
+// Initial array...
+var x0 = new Complex128Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+// Create an offset view...
+var x1 = new Complex128Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element
+
+// Fill every other element...
+var strt = new Complex128( 0.0, 0.0 );
+var stp = new Complex128( 2.0, 0.0 );
+
+zlogspace( 3, 10.0, strt, stp, true, x1, 2 );
+// x0 => [ 0.0, 0.0, 1.0, 0.0, 0.0, 0.0, 10.0, 0.0, 0.0, 0.0, 100.0, 0.0 ]
+```
+
+#### zlogspace.ndarray( N, base, start, stop, endpoint, x, strideX, offsetX )
+
+Fills a double-precision complex floating-point strided array with logarithmically spaced values over a specified interval using alternative indexing semantics.
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+
+var x = new Complex128Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+var strt = new Complex128( 0.0, 0.0 );
+var stp = new Complex128( 2.0, 0.0 );
+
+zlogspace.ndarray( x.length, 10.0, strt, stp, true, x, 1, 0 );
+// x => [ 1.0, 0.0, 10.0, 0.0, 100.0, 0.0 ]
+```
+
+The function has the following additional parameters:
+
+- **offsetX**: starting index.
+
+While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameter supports indexing semantics based on a starting index. For example, to access only the last three elements:
+
+
+
+```javascript
+var Complex128Array = require( '@stdlib/array/complex128' );
+var Complex128 = require( '@stdlib/complex/float64/ctor' );
+
+var x = new Complex128Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+var strt = new Complex128( 0.0, 0.0 );
+var stp = new Complex128( 2.0, 0.0 );
+
+zlogspace.ndarray( 3, 10.0, strt, stp, true, x, 1, x.length-3 );
+// x => [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 1.0, 0.0, 10.0, 0.0, 100.0, 0.0 ]
+```
+
+
+
+
+
+
+
+## Notes
+
+- Let `M` be the number of generated values (which is either `N` or `N+1` depending on whether `endpoint` is `true` or `false`, respectively). The complex increment between exponents is thus given by
+
+ ```text
+ Δ = (stop-start)/(M-1)
+ ```
+
+ and the generated values are equal to `base^(start+Δ*i)` for `i = 0, 1, ..., M-1`, where exponentiation is performed in the complex sense.
+
+- When the number of generated values is greater than `1` and `endpoint` is `true`, the set of values written to a provided input array is guaranteed to include the `base^start` and `base^stop` values. Beware, however, that values between `base^start` and `base^stop` are subject to floating-point rounding errors. Hence,
+
+ ```javascript
+ var Complex128Array = require( '@stdlib/array/complex128' );
+ var Complex128 = require( '@stdlib/complex/float64/ctor' );
+
+ var x = new Complex128Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+
+ var strt = new Complex128( 0.0, 0.0 );
+ var stp = new Complex128( 1.0, 0.0 );
+
+ zlogspace( 3, 10.0, strt, stp, true, x, 1 );
+ // x => [ 1.0, 0.0, ~3.162, 0.0, 10.0, 0.0 ]
+ ```
+
+ where `x[1]` is only guaranteed to be approximately equal to the square root of `10`.
+
+- When `N = 1` and `endpoint` is `false`, only the `base^start` value is written to a provided input array. When `N = 1` and `endpoint` is `true`, only the `base^stop` value is written to a provided input array.
+
+- Generated values follow a logarithmic spiral in the complex plane, where imaginary components of `start` and `stop` control phase rotation. If `Re(start) < Re(stop)`, the magnitudes of the generated values are in ascending order; otherwise, the magnitudes are in descending order.
+
+- If `N <= 0`, both functions return `x` unchanged.
+
+
+
+
+

+var Complex128Array = require( '@stdlib/array/complex128' );

+var logEach = require( '@stdlib/console/log-each' );
+var zlogspace = require( '@stdlib/blas/ext/base/zlogspace' );
+
+var x = new Complex128Array( 6 );
+
+var strt = new Complex128( 0.0, 0.0 );
+var stp = new Complex128( 5.0, 0.0 );
+
+zlogspace( x.length, 10.0, strt, stp, true, x, 1 );
+logEach( '%s', x );

+
+{{alias}}( N, base, start, stop, endpoint, x, strideX )
+ Fills a double-precision complex floating-point strided array with
+ logarithmically spaced values over a specified interval.
+
+ If `N = 1` and `endpoint` is `true`, the set of values written to an input
+ array only includes `base^stop`, but not `base^start`; otherwise, when
+ `N = 1` and `endpoint` is `false`, the set of values written to an input
+ array only includes `base^start`, but not `base^stop`.
+
+ Generated values follow a logarithmic spiral in the complex plane, where
+ imaginary components of `start` and `stop` control phase rotation. If the
+ real part of `start` is less than that of `stop`, the magnitudes of the
+ generated values will be in ascending order; otherwise, the magnitudes will
+ be in descending order.
+
+ When `N >= 2` and `endpoint` is `true`, the set of values written to an
+ input array is guaranteed to include the `base^start` and `base^stop`
+ values. Beware, however, that values between `base^start` and `base^stop`
+ are subject to floating-point rounding errors.
+
+ The `N` and stride parameters determine which elements in the strided array
+ are accessed at runtime.
+
+ Indexing is relative to the first index. To introduce an offset, use typed
+ array views.
+
+ If `N <= 0`, the function returns `x` unchanged.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ base: number
+ Base of the logarithmic scale.
+
+ start: Complex128
+ Exponent of the starting value.
+
+ stop: Complex128
+ Exponent of the final value.
+
+ endpoint: boolean
+ Boolean indicating whether to include the `base^stop` value when
+ writing values to the input array. If `false`, the function generates
+ `N+1` logarithmically spaced values over the interval `[base^start,
+ base^stop]` and only writes `N` values to the input array, thus
+ excluding `base^stop` from the input array. Accordingly, for a fixed
+ `N`, the spacing between adjacent values written to an input array
+ changes depending on the value of `endpoint`.
+
+ x: Complex128Array
+ Input array.
+
+ strideX: integer
+ Stride length.
+
+ Returns
+ -------
+ x: Complex128Array
+ Input array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );

+
+{{alias}}.ndarray( N, base, start, stop, endpoint, x, strideX, offsetX )
+ Fills a double-precision complex floating-point strided array with
+ logarithmically spaced values over a specified interval using alternative
+ indexing semantics.
+
+ While typed array views mandate a view offset based on the underlying
+ buffer, the offset parameter supports indexing semantics based on a starting
+ index.
+
+ Parameters
+ ----------
+ N: integer
+ Number of indexed elements.
+
+ base: number
+ Base of the logarithmic scale.
+
+ start: Complex128
+ Exponent of the starting value.
+
+ stop: Complex128
+ Exponent of the final value.
+
+ endpoint: boolean
+ Boolean indicating whether to include the `base^stop` value when
+ writing values to the input array. If `false`, the function generates
+ `N+1` logarithmically spaced values over the interval `[base^start,
+ base^stop]` and only writes `N` values to the input array, thus
+ excluding `base^stop` from the input array. Accordingly, for a fixed
+ `N`, the spacing between adjacent values written to an input array
+ changes depending on the value of `endpoint`.
+
+ x: Complex128Array
+ Input array.
+
+ strideX: integer
+ Stride length.
+
+ offsetX: integer
+ Starting index.
+
+ Returns
+ -------
+ x: Complex128Array
+ Input array.
+
+ Examples
+ --------
+ // Standard Usage:
+ > var x = new {{alias:@stdlib/array/complex128}}( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+ > var strt = new {{alias:@stdlib/complex/float64/ctor}}( 0.0, 0.0 );
+ > var stp = new {{alias:@stdlib/complex/float64/ctor}}( 2.0, 0.0 );
+ > {{alias}}.ndarray( x.length, 10.0, strt, stp, true, x, 1, 0 )
+ [ 1.0, 0.0, 10.0, 0.0, 100.0, 0.0 ]
+
+ // Using an index offset:
+ > x = new {{alias:@stdlib/array/complex128}}( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] );
+ > {{alias}}.ndarray( 3, 10.0, strt, stp, true, x, 1, 1 )
+ [ 0.0, 0.0, 1.0, 0.0, 10.0, 0.0, 100.0, 0.0 ]

+/**
+* Fills a double-precision complex floating-point strided array with logarithmically spaced values over a specified interval using alternative indexing semantics.
+*
+* ## Method
+*
+* 1. If \\( b \\) is a positive real number, exponentiation with base \\( b \\) and complex exponent \\( z \\) is defined by means of the exponential function with a complex argument as
+*
+* ```tex
+* b^z = e^{z \ln b}
+* ```
+*
+* where \\( \ln b \\) denotes the natural logarithm of \\( b \\).
+*
+* 2. Euler's formula states that, for any real number \\( y \\), one has
+*
+* ```tex
+* e^{iy} = \cos y + i \sin y
+* ```
+*
+* 3. Consequently, Euler's formula allows expressing the polar form of \\( b^z \\) in terms of the real and imaginary components of \\( z = x + iy \\).
+*
+* ```tex
+* b^{x + iy} = b^x ( \cos(y \ln b) + i \sin(y \ln b) )
+* ```
+*
+* which follows from
+*
+* ```tex
+* \begin{align*}
+* b^{x + iy} &= b^x b^{iy} \\
+* &= b^x e^{iy \ln b} \\
+* &= b^x ( \cos(y \ln b) + i \sin(y \ln b) ) \\
+* \end{align*}
+* ```
+*
+* 4. Using Euler's formulation thus provides an update equation for generating each logarithmically spaced element in which we compute the sine and cosine of the imaginary component of the exponent and multiply by a real-valued scalar.
+*
+* @param {PositiveInteger} N - number of indexed elements
+* @param {number} base - base of the logarithmic scale
+* @param {Complex128} start - exponent of the starting value
+* @param {Complex128} stop - exponent of the final value
+* @param {boolean} endpoint - boolean indicating whether to include the `base^stop` value when writing values to the input array
+* @param {Complex128Array} x - input array
+* @param {integer} strideX - stride length
+* @param {NonNegativeInteger} offsetX - starting index
+* @returns {Complex128Array} input array
+*
+* @example
+* var Complex128Array = require( '@stdlib/array/complex128' );
+* var Complex128 = require( '@stdlib/complex/float64/ctor' );

+/**
+* Fills a double-precision complex floating-point strided array with logarithmically spaced values over a specified interval using alternative indexing semantics.
+*
+* ## Method
+*
+* 1. If \\( b \\) is a positive real number, exponentiation with base \\( b \\) and complex exponent \\( z \\) is defined by means of the exponential function with a complex argument as
+*
+* ```tex
+* b^z = e^{z \ln b}
+* ```
+*
+* where \\( \ln b \\) denotes the natural logarithm of \\( b \\).
+*
+* 2. Euler's formula states that, for any real number \\( y \\), one has
+*
+* ```tex
+* e^{iy} = \cos y + i \sin y
+* ```
+*
+* 3. Consequently, Euler's formula allows expressing the polar form of \\( b^z \\) in terms of the real and imaginary components of \\( z = x + iy \\).
+*
+* ```tex
+* b^{x + iy} = b^x ( \cos(y \ln b) + i \sin(y \ln b) )
+* ```
+*
+* which follows from
+*
+* ```tex
+* \begin{align*}
+* b^{x + iy} &= b^x b^{iy} \\
+* &= b^x e^{iy \ln b} \\
+* &= b^x ( \cos(y \ln b) + i \sin(y \ln b) ) \\
+* \end{align*}
+* ```
+*
+* 4. Using Euler's formulation thus provides an update equation for generating each logarithmically spaced element in which we compute the sine and cosine of the imaginary component of the exponent and multiply by a real-valued scalar.
+*
+* @param N number of indexed elements
+* @param base base of the logarithmic scale
+* @param start exponent of the starting value
+* @param stop exponent of the final value
+* @param endpoint boolean indicating whether to include the `base^stop` value when writing values to the input array
+* @param X input array
+* @param strideX stride length
