@stdlib/array-base-from-strided v0.2.2

strided2array

Convert a strided array to a non-strided generic array.

Installation

npm install @stdlib/array-base-from-strided

Usage

var strided2array = require( '@stdlib/array-base-from-strided' );

strided2array( N, x, stride, offset )

Converts a strided array to a non-strided generic array.

var x = [ 1, 2, 3, 4, 5, 6 ];

var arr = strided2array( 3, x, 2, 0 );
// returns [ 1, 3, 5 ]

The function accepts the following arguments:

• N: number of indexed elements.
• x: input array.
• stride: index stride.
• offset: index of the first indexed value in the input array.

Notes

• The function assumes that the input array is compatible with the specified number of elements, index stride, and index offset.

Examples

var zeroTo = require( '@stdlib/array-base-zero-to' );
var strided2array = require( '@stdlib/array-base-from-strided' );

var x = zeroTo( 10 );
console.log( x );

var y = strided2array( 5, x, -2, x.length-1 );
console.log( y );
