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 [`Complex64Array`][@stdlib/array/complex64]. +- **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 Complex64Array = require( '@stdlib/array/complex64' ); +var Complex64 = require( '@stdlib/complex/float32/ctor' ); + +var x = new Complex64Array( [ 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 Complex64( 0.0, 0.0 ); +var stp = new Complex64( 3.0, 0.0 ); + +clogspace( 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.

For example, to access only the last three elements: + + + +```javascript +var Complex64Array = require( '@stdlib/array/complex64' ); +var Complex64 = require( '@stdlib/complex/float32/ctor' ); + +var x = new Complex64Array( [ 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 Complex64( 0.0, 0.0 ); +var stp = new Complex64( 2.0, 0.0 ); + +clogspace.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 Complex64Array = require( '@stdlib/array/complex64' ); + var Complex64 = require( '@stdlib/complex/float32/ctor' ); + + var x = new Complex64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] ); + + var strt = new Complex64( 0.0, 0.0 ); + var stp = new Complex64( 1.0, 0.0 ); + + clogspace( 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. + +
+ + + +
+ +## Examples + + + +```javascript +var Complex64Array = require( '@stdlib/array/complex64' ); +var Complex64 = require( '@stdlib/complex/float32/ctor' ); +var logEach = require( '@stdlib/console/log-each' ); +var clogspace = require( '@stdlib/blas/ext/base/clogspace' ); + +var x = new Complex64Array( 6 ); + +var strt = new Complex64( 0.0, 0.0 ); +var stp = new Complex64( 5.0, 0.0 ); + +clogspace( x.length, 10.0, strt, stp, true, x, 1 ); +logEach( '%s', x ); +``` + +
