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!
Scale a double-precision complex floating-point number by a real-valued double-precision floating-point scalar constant.
import scale from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-float64-base-scale@deno/mod.js';You can also import the following named exports from the package:
import { assign, strided } from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-float64-base-scale@deno/mod.js';Scales a double-precision complex floating-point number by a real-valued double-precision floating-point scalar constant.
import Complex128 from 'https://cdn.jsdelivr.net/gh/stdlib-js/complex-float64-ctor@deno/mod.js';
var z = new Complex128( 5.0, 3.0 );
var v = scale( 5.0, z );
// returns <Complex128>[ 25.0, 15.0 ]The function supports the following parameters:
- alpha: real-valued scalar constant.
- z: complex number.
Scales a double-precision complex floating-point number by a real-valued double-precision floating-point scalar constant and assigns results to a provided output array.
import Float64Array from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-float64@deno/mod.js';
var out = new Float64Array( 2 );
var v = scale.assign( 5.0, 5.0, 3.0, out, 1, 0 );
// returns <Float64Array>[ 25.0, 15.0 ]
var bool = ( out === v );
// returns trueThe function supports the following parameters:
- alpha: real-valued scalar constant.
- re: real component of the complex number.
- im: imaginary component of the complex number.
- out: output array.
- strideOut: stride length for
out. - offsetOut: starting index for
out.
Scales a double-precision complex floating-point number stored in a real-valued strided array view by a real-valued double-precision floating-point scalar constant and assigns results to a provided strided output array.

var v = scale.strided( 5.0, z, 1, 0, out, 1, 0 );
// returns <Float64Array>[ 25.0, 15.0 ]
var bool = ( out === v );
// returns trueThe function supports the following parameters:
- alpha: real-valued scalar constant.
- z: complex number strided array view.
- sz: stride length for
z. - oz: starting index for
z. - out: output array.
- so: stride length for
out. - oo: starting index for
out.
