strided2array5d

Convert a strided array to a five-dimensional nested array.

Usage

var strided2array5d = require( '@stdlib/array/base/strided2array5d' );

strided2array5d( x, shape, strides, offset )

Converts a strided array to a five-dimensional nested array.

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

var arr = strided2array5d( x, [ 1, 1, 1, 3, 2 ], [ 6, 6, 6, 2, 1 ], 0 );
// returns [ [ [ [ [ 1, 2 ], [ 3, 4 ], [ 5, 6 ] ] ] ] ]

arr = strided2array5d( x, [ 1, 1, 1, 3, 2 ], [ 1, 1, 1, 1, 3 ], 0 );
// returns [ [ [ [ [ 1, 4 ], [ 2, 5 ], [ 3, 6 ] ] ] ] ]

The function accepts the following arguments:

x: input array.
shape: array shape.
strides: dimension strides.
offset: index of the first indexed value in the input array.

Notes

The function assumes that the input array is compatible with the specified array shape, dimension strides, and index offset.

Examples

var zeroTo = require( '@stdlib/array/base/zero-to' );
var numel = require( '@stdlib/ndarray/base/numel' );
var shape2strides = require( '@stdlib/ndarray/base/shape2strides' );
var strided2array5d = require( '@stdlib/array/base/strided2array5d' );

var shape = [ 1, 1, 3, 3, 3 ];

var x = zeroTo( numel( shape ) );
console.log( x );

var y = strided2array5d( x, shape, shape2strides( shape, 'row-major' ), 0 );
console.log( y );

y = strided2array5d( x, shape, shape2strides( shape, 'column-major' ), 0 );
console.log( y );
