+ +This BLAS extension implements the operation + + + +```math +\mathbf{y} = \mathbf{x} \oslash \mathbf{y} +``` + + + +
+ + + +
+ +## Usage + +```javascript +var zxdy = require( '@stdlib/blas/ext/base/zxdy' ); +``` + +#### zxdy( N, x, strideX, y, strideY ) + +Divides elements of a double-precision complex floating-point strided array `x` by the corresponding elements of a double-precision complex floating-point strided array `y` and assigns the results to `y`. + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +var x = new Complex128Array( [ 4.0, 6.0, 12.0, 8.0, 16.0, 8.0 ] ); +var y = new Complex128Array( [ 1.0, 1.0, 2.0, 2.0, 4.0, 4.0 ] ); + +zxdy( x.length, x, 1, y, 1 ); +// y => [ 5.0, 1.0, 5.0, -1.0, 3.0, -1.0 ] +``` + +The function has the following parameters: + +- **N**: number of indexed elements. +- **x**: input [`Complex128Array`][@stdlib/array/complex128]. +- **strideX**: stride length for `x`. +- **y**: output [`Complex128Array`][@stdlib/array/complex128]. +- **strideY**: stride length for `y`. + +The `N` and stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to divide every other element of `x` by every other element of `y`: + + + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +var x = new Complex128Array( [ 4.0, 6.0, 100.0, 200.0, 12.0, 8.0, 300.0, 400.0 ] ); +var y = new Complex128Array( [ 1.0, 1.0, 500.0, 600.0, 2.0, 2.0, 700.0, 800.0 ] ); + +zxdy( 2, x, 2, y, 2 ); +// y => [ 5.0, 1.0, 500.0, 600.0, 5.0, -1.0, 700.0, 800.0 ] +``` + +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' ); + +// Initial arrays... +var x0 = new Complex128Array( [ 100.0, 200.0, 4.0, 6.0, 12.0, 8.0, 16.0, 8.0, 300.0, 400.0 ] ); +var y0 = new Complex128Array( [ 500.0, 600.0, 700.0, 800.0, 1.0, 1.0, 2.0, 2.0, 4.0, 4.0 ] ); + +// Create offset views... +var x1 = new Complex128Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element +var y1 = new Complex128Array( y0.buffer, y0.BYTES_PER_ELEMENT*2 ); // start at 3rd element + +zxdy( 3, x1, 1, y1, 1 ); +// y0 => [ 500.0, 600.0, 700.0, 800.0, 5.0, 1.0, 5.0, -1.0, 3.0, -1.0 ] +``` + +#### zxdy.ndarray( N, x, strideX, offsetX, y, strideY, offsetY ) + +Divides elements of a double-precision complex floating-point strided array `x` by the corresponding elements of a double-precision complex floating-point strided array `y` and assigns the results to `y` using alternative indexing semantics. + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +var x = new Complex128Array( [ 4.0, 6.0, 12.0, 8.0, 16.0, 8.0 ] ); +var y = new Complex128Array( [ 1.0, 1.0, 2.0, 2.0, 4.0, 4.0 ] ); + +zxdy.ndarray( x.length, x, 1, 0, y, 1, 0 ); +// y => [ 5.0, 1.0, 5.0, -1.0, 3.0, -1.0 ] +``` + +The function has the following additional parameters: + +- **offsetX**: starting index for `x`. +- **offsetY**: starting index for `y`. + +While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameters support indexing semantics based on starting indices. For example, to divide the last three elements of `x` by the last three elements of `y`: + + + +```javascript +var Complex128Array = require( '@stdlib/array/complex128' ); + +var x = new Complex128Array( [ 100.0, 200.0, 300.0, 400.0, 4.0, 6.0, 12.0, 8.0, 16.0, 8.0 ] ); +var y = new Complex128Array( [ 500.0, 600.0, 700.0, 800.0, 1.0, 1.0, 2.0, 2.0, 4.0, 4.0 ] ); + +zxdy.ndarray( 3, x, 1, x.length-3, y, 1, y.length-3 ); +// y => [ 500.0, 600.0, 700.0, 800.0, 5.0, 1.0, 5.0, -1.0, 3.0, -1.0 ] +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return `y` unchanged. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var Complex128Array = require( '@stdlib/array/complex128' ); +var logEach = require( '@stdlib/console/log-each' ); +var zxdy = require( '@stdlib/blas/ext/base/zxdy' ); + +var xbuf = discreteUniform( 20, -100, 100, { + 'dtype': 'float64' +}); +var ybuf = discreteUniform( 20, 1, 100, { + 'dtype': 'float64' +}); +var x = new Complex128Array( xbuf.buffer ); +var y = new Complex128Array( ybuf.buffer ); + +zxdy( x.length, x, 1, y, 1 ); +logEach( '%s', y ); +``` + +
