Must be either `'row-major'` or `'column-major'`. +- **N**: number of indexed elements. +- **x**: input [`Array`][mdn-array] or [`typed array`][mdn-typed-array]. +- **strideX**: stride length for `x`. +- **out**: output [`Array`][mdn-array] or [`typed array`][mdn-typed-array]. +- **LDO**: stride length between successive contiguous vectors of the matrix `out` (a.k.a., leading dimension of `out`). + +The `N` and stride parameters determine which elements in the strided arrays are accessed at runtime. For example, to compute the Cartesian square of every other element: + +```javascript +var x = [ 1.0, 0.0, 2.0, 0.0 ]; +var out = [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]; + +gcartesianSquare( 'row-major', 2, x, 2, out, 2 ); +// 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 + +// Output array: +var out = new Float64Array( 8 ); + +gcartesianSquare( 'row-major', 2, x1, 1, out, 2 ); +// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ] +``` + + + +#### gcartesianSquare.ndarray( N, x, strideX, offsetX, out, strideOut1, strideOut2, offsetOut ) + + + +Computes the Cartesian square for a strided array using alternative indexing semantics. + +```javascript +var x = [ 1.0, 2.0 ]; +var out = [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]; + +gcartesianSquare.ndarray( x.length, x, 1, 0, out, 2, 1, 0 ); +// out => [ 1.0, 1.0, 1.0, 2.0, 2.0, 1.0, 2.0, 2.0 ] +``` + +The function has the following parameters: + +- **N**: number of indexed elements. +- **x**: input [`Array`][mdn-array] or [`typed array`][mdn-typed-array]. +- **strideX**: stride length for `x`. +- **offsetX**: starting index for `x`. +- **out**: output [`Array`][mdn-array] or [`typed array`][mdn-typed-array]. +- **strideOut1**: stride length for the first dimension of `out`. +- **strideOut2**: stride length for the second dimension of `out`. +- **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 x = [ 0.0, 0.0, 1.0, 2.0 ]; +var out = [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]; + +gcartesianSquare.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 + +- Pairs are stored as rows in the output matrix, where the first column contains the first element of each pair and the second column contains the second element. +- For an input array of length `N`, the output array must contain at least `N * N * 2` indexed elements. +- For row-major order, the `LDO` parameter must be greater than or equal to `2`. For column-major order, the `LDO` parameter must be greater than or equal to `max(1,N*N)`. +- If `N <= 0`, both functions return `out` unchanged. +- Both functions support array-like objects having getter and setter accessors for array element access (e.g., [`@stdlib/array/base/accessor`][@stdlib/array/base/accessor]). +- Depending on the environment, the typed versions ([`dcartesianSquare`][@stdlib/blas/ext/base/dcartesian-square], [`scartesianSquare`][@stdlib/blas/ext/base/scartesian-square], etc.) are likely to be significantly more performant. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var zeros = require( '@stdlib/array/zeros' ); +var gcartesianSquare = require( '@stdlib/blas/ext/base/gcartesian-square' ); + +var N = 2; +var x = discreteUniform( N, 1, 10, { + 'dtype': 'generic' +}); +console.log( x ); + +var out = zeros( N*N*2, 'generic' ); +gcartesianSquare( 'row-major', N, x, 1, out, 2 ); +console.log( out ); +``` + +
