About stdlib...
</summary>
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!
reinterpret
[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
Reinterpret a [
Complex64Array][@stdlib/array/complex64] as a [Float32Array][@stdlib/array/float32].
bash
npm install @stdlib/strided-base-reinterpret-complex64
javascript
var reinterpret = require( '@stdlib/strided-base-reinterpret-complex64' );
#### reinterpret( x, offset )
Returns a [Float32Array][@stdlib/array/float32] view of a [Complex64Array][@stdlib/array/complex64].
javascript
var Complex64Array = require( '@stdlib/array-complex64' );
var x = new Complex64Array( 10 );
var view = reinterpret( x, 0 );
// returns <Float32Array>
var bool = ( view.buffer === x.buffer );
// returns true
var len = view.length;
// returns 20
The offset argument specifies the starting index of the returned [Float32Array][@stdlib/array/float32] view relative to the [Complex64Array][@stdlib/array/complex64].
javascript
var Complex64Array = require( '@stdlib/array-complex64' );
var x = new Complex64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
var view = reinterpret( x, 2 );
// returns <Float32Array>
var len = view.length;
// returns 4
var re = view[ 0 ];
// returns 5.0
var im = view[ 1 ];
// returns 6.0
javascript
var Complex64Array = require( '@stdlib/array-complex64' );
var real = require( '@stdlib/complex-float64-real' );
var imag = require( '@stdlib/complex-float64-imag' );
var reinterpret = require( '@stdlib/strided-base-reinterpret-complex64' );
// Define a complex number array:
var x = new Complex64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0 ] );
// returns <Complex64Array>
// Reinterpret as a `float32` array:
var view = reinterpret( x, 0 );
// returns <Float32Array>
// Set view elements:
view[ 0 ] = 9.0;
view[ 1 ] = 10.0;
// Get the first element of the complex number array:
var z = x.get( 0 );
// returns <Complex64>
var re = real( z );
// returns 9.0
var im = imag( z );
// returns 10.0
