We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

Compute the cube root of each element retrieved from an input strided array via a callback function.

## Installation ```bash npm install @stdlib/math-strided-special-cbrt-by ``` Alternatively, - To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]). - If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions). - For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]). The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships. To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.

## Usage ```javascript var cbrtBy = require( '@stdlib/math-strided-special-cbrt-by' ); ``` #### cbrtBy( N, x, strideX, y, strideY, clbk\[, thisArg] ) Computes the [cube root][@stdlib/math/base/special/cbrt] of each element retrieved from an input strided array `x` via a callback function and assigns each result to an element in an output strided array `y`. ```javascript function accessor( v ) { return v; } var x = [ 1.0, 9.0, -27.0, 81.0, -125.0 ]; var y = [ 0.0, 0.0, 0.0, 0.0, 0.0 ]; cbrtBy( x.length, x, 1, y, 1, accessor ); // y => [ 1.0, ~2.08, -3.0, ~4.327, -5.0 ] ``` The function accepts the following arguments: - **N**: number of indexed elements. - **x**: input [`Array`][mdn-array], [`typed array`][mdn-typed-array], or an array-like object (excluding strings and functions). - **strideX**: index increment for `x`. - **y**: output [`Array`][mdn-array], [`typed array`][mdn-typed-array], or an array-like object (excluding strings and functions). - **strideY**: index increment for `y`. - **clbk**: callback function. - **thisArg**: execution context (_optional_). The invoked callback function is provided six arguments: - **value**: input array element. - **idx**: iteration index (zero-based). - **xi**: input array strided index (`offsetX + idx*strideX`). - **yi**: output array strided index (`offsetY + idx*strideY`). - **x**: input array/collection. - **y**: output array/collection. To set the callback execution context, provide a `thisArg`. ```javascript function accessor( v ) { this.count += 1; return v; } var context = { 'count': 0 }; var x = [ 1.0, 9.0, -27.0, 81.0, -125.0 ]; var y = [ 0.0, 0.0, 0.0, 0.0, 0.0 ]; cbrtBy( x.length, x, 1, y, 1, accessor, context ); // y => [ 1.0, ~2.08, -3.0, ~4.327, -5.0 ] var cnt = context.count; // returns 5 ``` The `N` and `stride` parameters determine which elements in `x` and `y` are accessed at runtime. For example, to index every other value in `x` and to index the first `N` elements of `y` in reverse order, ```javascript function accessor( v ) { return v; } var x = [ 1.0, 9.0, -27.0, 81.0, -125.0, -9.14 ]; var y = [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]; cbrtBy( 3, x, 2, y, -1, accessor ); // y => [ -5.0, -3.0, 1.0, 0.0, 0.0, 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' ); function accessor( v ) { return v; } // Initial arrays... var x0 = new Float64Array( [ 1.0, 9.0, -27.0, 81.0, -125.0, -9.14 ] ); var y0 = new Float64Array( [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ] ); // Create offset views... var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element var y1 = new Float64Array( y0.buffer, y0.BYTES_PER_ELEMENT*3 ); // start at 4th element cbrtBy( 3, x1, -2, y1, 1, accessor ); // y0 => [ 0.0, 0.0, 0.0, ~-2.091, ~4.327, ~2.08 ] ``` #### cbrtBy.ndarray( N, x, strideX, offsetX, y, strideY, offsetY, clbk\[, thisArg] ) Computes the [cube root][@stdlib/math/base/special/cbrt] of each element retrieved from an input strided array `x` via a callback function and assigns each result to an element in an output strided array `y` using alternative indexing semantics. ```javascript function accessor( v ) { return v; } var x = [ 1.0, 9.0, -27.0, 81.0, -125.0 ]; var y = [ 0.0, 0.0, 0.0, 0.0, 0.0 ]; cbrtBy.ndarray( x.length, x, 1, 0, y, 1, 0, accessor ); // y => [ 1.0, ~2.08, -3.0, ~4.327, -5.0 ] ``` The function accepts the following additional arguments: - **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 `offsetX` and `offsetY` parameters support indexing semantics based on starting indices. For example, to index every other value in `x` starting from the second value and to index the last `N` elements in `y`, ```javascript function accessor( v ) { return v; } var x = [ 1.0, 9.0, -27.0, 81.0, -125.0, -9.14 ]; var y = [ 0.0, 0.0, 0.0, 0.0, 0.0, 0.0 ]; cbrtBy.ndarray( 3, x, 2, 1, y, -1, y.length-1, accessor ); // y => [ 0.0, 0.0, 0.0, ~-2.091, ~4.327, ~2.08 ] ```

## Notes - If a provided callback function does not return any value (or equivalently, explicitly returns `undefined`), the value is **ignored**. ```javascript function accessor() { // No-op... } var x = [ 1.0, 9.0, -27.0, 81.0, -125.0 ]; var y = [ 0.0, 0.0, 0.0, 0.0, 0.0 ]; cbrtBy( x.length, x, 1, y, 1, accessor ); // y => [ 0.0, 0.0, 0.0, 0.0, 0.0 ] ```

## Examples ```javascript var uniform = require( '@stdlib/random-base-uniform' ).factory; var filledarray = require( '@stdlib/array-filled' ); var filledarrayBy = require( '@stdlib/array-filled-by' ); var cbrtBy = require( '@stdlib/math-strided-special-cbrt-by' ); function accessor( v, i ) { if ( (i%3) === 0 ) { // Simulate a "missing" value... return; } return v; } var x = filledarrayBy( 10, 'generic', uniform( -10.0, 10.0 ) ); console.log( x ); var y = filledarray( null, 10, 'generic' ); console.log( y ); cbrtBy.ndarray( x.length, x, 1, 0, y, -1, y.length-1, accessor ); console.log( y ); ```
