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!
Return a new ndarray with the element at a specified index replaced by a provided value.
npm install @stdlib/ndarray-withAlternatively,
- 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 ndarrayWith = require( '@stdlib/ndarray-with' );Returns a new ndarray with the element at a specified index replaced by a provided value.
var zeros = require( '@stdlib/ndarray-zeros' );
var x = zeros( [ 2, 2 ], {
'dtype': 'float64'
});
// returns <ndarray>
var out = ndarrayWith( x, [ 0, 0 ], 1.0 );
// returns <ndarray>
var v = out.get( 0, 0 );
// returns 1.0The function accepts the following arguments:
- x: input ndarray.
- indices: indices of the element to replace.
- value: replacement value.
- This function does not validate that a provided
valueis compatible with the data type of the input ndarray. For example, the function does not guard against precision loss whenvalueis a real-valued number and the input ndarray has an integer data type. This function should be considered a copy-on-write analog to using an ndarray'ssetmethod. Whether avalueis silently coerced to the data type of the input ndarray or triggers an exception when incompatible is implementation-dependent. Accordingly, any assertion logic ensuring data type compatibility should be performed before calling this function.
var zeros = require( '@stdlib/ndarray-zeros' );
var ndarray2array = require( '@stdlib/ndarray-to-array' );
var ndarrayWith = require( '@stdlib/ndarray-with' );
var x = zeros( [ 1, 3, 3 ], {
'dtype': 'float64'
});
var out = ndarrayWith( x, [ 0, 1, 1 ], 10.0 );
console.log( ndarray2array( out ) );This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
