+# 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 ]
