For example, to compute the cumulative [range][range] of every other element in `x` and store the results in every other element of y, + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, 2.0, 2.0, -7.0, -2.0, 3.0, 4.0, 2.0 ] ); +var y = new Float32Array( x.length ); + +scurange( 4, x, 2, y, 2 ); +// y => [ 0.0, 0.0, 1.0, 0.0, 4.0, 0.0, 6.0, 0.0 ] +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + + + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +// Input array: +var x0 = new Float32Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] ); + +// Create a view of x0 starting at the 2nd element: +var x1 = new Float32Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); + +// Create an output array: +var y0 = new Float32Array( x0.length ); + +// Create a view of y0 starting at the 2nd element: +var y1 = new Float32Array( y0.buffer, y0.BYTES_PER_ELEMENT*1 ); + +scurange( 3, x1, 2, y1, 2 ); +// y0 => [ 0.0, 0.0, 0.0, 2.0, 0.0, 4.0 ] +``` + +#### scurange.ndarray + +```text +scurange.ndarray( N, x, strideX, offsetX, y, strideY, offsetY ) + + +Computes the cumulative [range][range] of a single-precision floating-point strided array using alternative indexing semantics. + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 1.0, -2.0, 2.0 ] ); +var y = new Float32Array( x.length ); + +scurange.ndarray( x.length, x, 1, 0, y, 1, 0 ); +// y => [ 0.0, 3.0, 4.0 ] +``` + +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 parameter supports indexing semantics based on a starting index. For example, to calculate the [range][range] for every other element in `x` starting from the second element and store the results in y starting from the first element: + +```javascript +var Float32Array = require( '@stdlib/array/float32' ); + +var x = new Float32Array( [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0 ] ); +var y = new Float32Array( 4 ); + +scurange.ndarray( 4, x, 2, 1, y, 1, 0 ); +// y => [ 0.0, 3.0, 4.0, 6.0 ] +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return the output array `y` unchanged. +- If an indexed input value is `NaN`, all subsequent output values are `NaN`. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var Float32Array = require( '@stdlib/array/float32' ); +var scurange = require( '@stdlib/stats/strided/scurange' ); + +var x = discreteUniform( 10, -50, 50, { + 'dtype': 'float32' +}); +var y = new Float32Array( x.length ); + +console.log( x ); +console.log( y ); + +scurange( x.length, x, 1, y, 1 ); + +console.log( y ); +``` + +
