+ +## Usage + +```javascript +var gzeroTo = require( '@stdlib/blas/ext/base/gzero-to' ); +``` + +#### gzeroTo( N, x, strideX ) + +Fills a strided array with linearly spaced numeric elements which increment by `1` starting from zero. + +```javascript +var x = [ 0.0, 0.0, 0.0, 0.0 ]; + +gzeroTo( x.length, x, 1 ); +// x => [ 0.0, 1.0, 2.0, 3.0 ] +``` + +The function has the following parameters: + +- **N**: number of indexed elements. +- **x**: input array. +- **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 x = [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]; + +gzeroTo( 3, x, 2 ); +// x => [ 0.0, 0.0, 1.0, 0.0, 2.0, 0.0 ] +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +// Initial array... +var x0 = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] ); + +// Create an offset view... +var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element + +// Fill every other element... +gzeroTo( 3, x1, 2 ); +// x0 => [ 0.0, 0.0, 0.0, 1.0, 0.0, 2.0 ] +``` + +#### gzeroTo.ndarray( N, x, strideX, offsetX ) + +Fills a strided array with linearly spaced numeric elements which increment by `1` starting from zero using alternative indexing semantics. + +```javascript +var x = [ 0.0, 0.0, 0.0, 0.0 ]; + +gzeroTo.ndarray( x.length, x, 1, 0 ); +// x => [ 0.0, 1.0, 2.0, 3.0 ] +``` + +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 x = [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]; + +gzeroTo.ndarray( 3, x, 1, x.length-3 ); +// x => [ 0.0, 0.0, 0.0, 0.0, 1.0, 2.0 ] +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return `x` unchanged. +- Both functions support array-like objects having getter and setter accessors for array element access (e.g., [`@stdlib/array/complex64`][@stdlib/array/complex64]). +- Depending on the environment, the typed versions ([`dzeroTo`][@stdlib/blas/ext/base/dzero-to], [`szeroTo`][@stdlib/blas/ext/base/szero-to], etc.) are likely to be significantly more performant. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var gzeroTo = require( '@stdlib/blas/ext/base/gzero-to' ); + +var x = discreteUniform( 10, -100, 100, { + 'dtype': 'generic' +}); +console.log( x ); + +gzeroTo( x.length, x, 1 ); +console.log( x ); +``` + +
