For example, to compute the Cartesian square of every other element: + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 1.0, 0.0, 2.0, 0.0 ] ); +var out = new Float64Array( 8 ); + +dcartesianSquare( 2, x, 2, out, 2, 1 ); +// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ] +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +// Initial array... +var x0 = new Float64Array( [ 0.0, 1.0, 2.0, 3.0 ] ); + +// Create an offset view... +var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element + +// Compute the Cartesian square of the first two elements of the view: +var out = new Float64Array( 8 ); +dcartesianSquare( 2, x1, 1, out, 2, 1 ); +// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ] +``` + + + +#### dcartesianSquare.ndarray( N, x, strideX, offsetX, out, strideOut1, strideOut2, offsetOut ) + +Computes the Cartesian square for a double-precision floating-point strided array using alternative indexing semantics. + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 1.0, 2.0, 3.0 ] ); +var out = new Float64Array( 18 ); + +dcartesianSquare.ndarray( x.length, x, 1, 0, out, 2, 1, 0 ); +// out => [ 1.0, 1.0, 1.0, 2.0, 1.0, 3.0, 2.0, 1.0, 2.0, 2.0, 2.0, 3.0, 3.0, 1.0, 3.0, 2.0, 3.0, 3.0 ] +``` + +The function has the following additional parameters: + +- **offsetX**: starting index for `x`. +- **offsetOut**: starting index for `out`. + +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 access only the last two elements: + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var x = new Float64Array( [ 0.0, 0.0, 1.0, 2.0 ] ); +var out = new Float64Array( 8 ); + +dcartesianSquare.ndarray( 2, x, 1, 2, out, 2, 1, 0 ); +// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ] +``` + +
+ + + +
+ +## Notes + +- For an input array `x` of length `N`, the output array `out` must contain at least `N^2` pairs. +- If `N <= 0`, both functions return `out` unchanged. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var Float64Array = require( '@stdlib/array/float64' ); +var dcartesianSquare = require( '@stdlib/blas/ext/base/dcartesian-square' ); + +var N = 4; +var x = discreteUniform( N, 1, 10, { + 'dtype': 'float64' +}); +console.log( x ); + +var out = new Float64Array( N * N * 2 ); +dcartesianSquare( N, x, 1, out, 2, 1 ); +console.log( out ); +``` + +
