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!
Assign element values from a broadcasted input array to corresponding elements in an output array.
import sliceAssign from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-fancy-slice-assign@esm/index.mjs';Assigns element values from a broadcasted input array to corresponding elements in an output array.
import Slice from 'https://cdn.jsdelivr.net/gh/stdlib-js/slice-ctor@esm/index.mjs';
var x = [ 1, 2, 3, 4 ];
var y = [ 0, 0, 0, 0, 0, 0, 0, 0 ];
var s = new Slice( null, null, -2 );
// returns <Slice>
var out = sliceAssign( x, y, s, false );
// returns [ 0, 4, 0, 3, 0, 2, 0, 1 ]
var bool = ( out === y );
// returns trueThe function supports the following parameters:
- x: input array.
- y: output array.
- s: slice object specifying the output array slice.
- strict: boolean indicating whether to enforce strict bounds checking.
- The input array must be broadcast compatible with the output array slice (i.e., contain only one element or the same number of elements as in the slice).
- The input array must have a data type which can be safely cast to the output array data type. Floating-point data types (both real and complex) are allowed to downcast to a lower precision data type of the same kind (e.g., element values from a
'float64'input array can be assigned to corresponding elements in a'float32'output array).
