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!
Replace elements in a one-dimensional ndarray not equal to a provided search element with a specified scalar constant.
import gfillNotEqual from 'https://cdn.jsdelivr.net/gh/stdlib-js/blas-ext-base-ndarray-gfill-not-equal@esm/index.mjs';Replaces elements in a one-dimensional ndarray not equal to a provided search element with a specified scalar constant.
import vector from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-vector-ctor@esm/index.mjs';
import scalar2ndarray from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-from-scalar@esm/index.mjs';
var x = vector( [ 0.0, -2.0, 3.0, 0.0, 4.0, -6.0 ], 'generic' );
var searchElement = scalar2ndarray( 0.0, {
'dtype': 'generic'
});
var alpha = scalar2ndarray( 5.0, {
'dtype': 'generic'
});
gfillNotEqual( [ x, searchElement, alpha ] );
// x => <ndarray>[ 0.0, 5.0, 5.0, 0.0, 5.0, 5.0 ]The function has the following parameters:
-
arrays: array-like object containing the following ndarrays:
- a one-dimensional input ndarray.
- a zero-dimensional ndarray containing the search element.
- a zero-dimensional ndarray containing the scalar constant.
- The input ndarray is modified in-place (i.e., the input ndarray is mutated).
- When comparing elements, the function checks for equality using the strict equality operator
===. As a consequence,NaNvalues are considered distinct (i.e., asNaN !== NaNalways evaluates totrue,NaNelements are always replaced), and-0and+0are considered the same.
