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!
fullLike
Create a filled array having the same length and data type as a provided array.
Installation
npm install @stdlib/array-full-like
Usage
var fullLike = require( '@stdlib/array-full-like' );
fullLike( x, value[, dtype] )
Creates a filled array having the same length and data type as a provided array x.
var x = [ 1, 2, 3, 4, 5 ];
var arr = fullLike( x, 1 );
// returns [ 1, 1, 1, 1, 1 ]
The function supports the following data types:
float64: double-precision floating-point numbers (IEEE 754)float32: single-precision floating-point numbers (IEEE 754)complex128: double-precision complex floating-point numberscomplex64: single-precision complex floating-point numbersint32: 32-bit two's complement signed integersuint32: 32-bit unsigned integersint16: 16-bit two's complement signed integersuint16: 16-bit unsigned integersint8: 8-bit two's complement signed integersuint8: 8-bit unsigned integersuint8c: 8-bit unsigned integers clamped to 0-255generic: generic JavaScript values
By default, the output array data type is inferred from the provided array x. To return an array having a different data type, provide a dtype argument.
var x = [ 1, 1 ];
var arr = fullLike( x, 1, 'int32' );
// returns <Int32Array>[ 1, 1 ]
Notes
- If provided a number and the output array data type is a complex number data type, the function returns a complex number array where each element has a real component whose value equals the provided fill value and where each element has an imaginary component equal to
0.
Examples
var dtypes = require( '@stdlib/array-dtypes' );
var zeros = require( '@stdlib/array-zeros' );
var fullLike = require( '@stdlib/array-full-like' );
// Create a zero-filled array:
var x = zeros( 4, 'complex128' );
// Get a list of array data types:
var dt = dtypes();
// Generate filled arrays...
var y;
var i;
for ( i = 0; i < dt.length; i++ ) {
y = fullLike( x, 1.0, dt[ i ] );
console.log( y );
}
Notice
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.
