About stdlib...
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!
Convert a strided array to a four-dimensional nested array.
import strided2array4d from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-strided2array4d@deno/mod.js';Converts a strided array to a four-dimensional nested array.
var x = [ 1, 2, 3, 4, 5, 6 ];
var arr = strided2array4d( x, [ 1, 1, 3, 2 ], [ 6, 6, 2, 1 ], 0 );
// returns [ [ [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ] ] ]
arr = strided2array4d( x, [ 1, 1, 3, 2 ], [ 1, 1, 1, 3 ], 0 );
// returns [ [ [ [ 1, 4 ], [ 2, 5 ], [ 3, 6 ] ] ] ]The function accepts the following arguments:
- x: input array.
- shape: array shape.
- strides: dimension strides.
- offset: index of the first indexed value in the input array.
- The function assumes that the input array is compatible with the specified array shape, dimension strides, and index offset.
