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!
Remove singleton dimensions.
import removeSingletonDimensions from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-base-remove-singleton-dimensions@esm/index.mjs';Returns an ndarray without singleton dimensions (i.e., dimensions whose size is equal to 1).
import array from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-array@esm/index.mjs';
// Create a 1x2x2 ndarray:
var x = array( [ [ [ 1, 2 ], [ 3, 4 ] ] ] );
// returns <ndarray>[ [ [ 1, 2 ], [ 3, 4 ] ] ]
// Remove singleton dimensions:
var y = removeSingletonDimensions( x, false );
// returns <ndarray>[ [ 1, 2 ], [ 3, 4 ] ]The function accepts the following arguments:
- x: input ndarray.
- writable: boolean indicating whether a returned ndarray should be writable.
- The
writableparameter only applies to ndarray constructors supporting read-only instances. - The function always returns a new ndarray instance even if the input ndarray does not contain any singleton dimensions.
