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!
Apply a unary callback to elements in a four-dimensional nested input array and assign results to elements in a four-dimensional nested output array.
import unary4d from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-unary4d@esm/index.mjs';Applies a unary callback to elements in a four-dimensional nested input array and assigns results to elements in a four-dimensional nested output array.
import abs from 'https://cdn.jsdelivr.net/gh/stdlib-js/math-base-special-abs@esm/index.mjs';
var x = [ [ [ [ -1.0, -2.0 ], [ -3.0, -4.0 ] ] ] ];
var shape = [ 1, 1, 2, 2 ];
// Compute the absolute values in-place:
unary4d( [ x, x ], shape, abs );
// x => [ [ [ [ 1.0, 2.0 ], [ 3.0, 4.0 ] ] ] ]The function accepts the following arguments:
- arrays: array-like object containing one input nested array and one output nested array.
- shape: array shape.
- fcn: unary function to apply.
- The function assumes that the input and output arrays have the same shape.
