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!
Sort a one-dimensional ndarray.
npm install @stdlib/blas-ext-base-ndarray-gsortAlternatively,
- To load the package in a website via a
scripttag without installation and bundlers, use the ES Module available on theesmbranch (see README). - If you are using Deno, visit the
denobranch (see README for usage intructions). - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umdbranch (see README).
The branches.md 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.
var gsort = require( '@stdlib/blas-ext-base-ndarray-gsort' );Sorts a one-dimensional ndarray.
var scalar2ndarray = require( '@stdlib/ndarray-from-scalar' );
var array = require( '@stdlib/ndarray-array' );
var x = array( [ 1.0, -2.0, 3.0, -4.0 ], {
'dtype': 'generic'
});
var order = scalar2ndarray( 1.0, {
'dtype': 'generic'
});
var out = gsort( [ x, order ] );
// returns <ndarray>[ -4.0, -2.0, 1.0, 3.0 ]The function has the following parameters:
- arrays: array-like object containing a one-dimensional input ndarray and a zero-dimensional ndarray specifying the sort order.
- The input ndarray is sorted in-place (i.e., the input ndarray is mutated).
- When the sort order is less than zero, the input ndarray is sorted in decreasing order. When the sort order is greater than zero, the input ndarray is sorted in increasing order. When the sort order is equal to zero, the input ndarray is left unchanged.
