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!

bind2vind

Convert a linear index in an underlying data buffer to a linear index in an array view.

Installation

1npm install @stdlib/ndarray-base-bind2vind

Usage

1var bind2vind = require( '@stdlib/ndarray-base-bind2vind' );

bind2vind( shape, strides, offset, order, idx, mode )

Converts a linear index in an underlying data buffer to a linear index in an array view.

1var shape = [ 3, 3 ];
2var order = 'row-major';
3var strides = [ -3, 1 ];
4var offset = 6;
5
6var idx = bind2vind( shape, strides, offset, order, 7, 'throw' );
7// returns 1

The function supports the following modes:

throw: specifies that the function should throw an error when a linear index exceeds array dimensions.
normalize: specifies that the function should normalize negative indices and should throw an error when a linear index exceeds array dimensions.
wrap: specifies that the function should wrap around a linear index exceeding array dimensions using modulo arithmetic.
clamp: specifies that the function should set a linear index exceeding array dimensions to either 0 (minimum linear index) or the maximum linear index.

1var shape = [ 2, 2 ];
2var order = 'row-major';
3var strides = [ -2, 1 ];
4var offset = 2;
5
6var idx = bind2vind( shape, strides, offset, order, -2, 'wrap' );
7// returns 0
8
9idx = bind2vind( shape, strides, offset, order, 10, 'clamp' );
10// returns 1

The order parameter specifies whether an array is row-major (C-style) or column-major (Fortran-style).

1var shape = [ 2, 2 ];
2var order = 'column-major';
3var strides = [ 1, -2 ];
4var offset = 2;
5
6var idx = bind2vind( shape, strides, offset, order, 2, 'throw' );
7// returns 0

Examples

1var shape2strides = require( '@stdlib/ndarray-base-shape2strides' );
2var strides2offset = require( '@stdlib/ndarray-base-strides2offset' );
3var numel = require( '@stdlib/ndarray-base-numel' );
4var randu = require( '@stdlib/random-base-randu' );
5var bind2vind = require( '@stdlib/ndarray-base-bind2vind' );
6
7// Specify array meta data:
8var shape = [ 3, 3, 3 ];
9var order = 'row-major';
10
11// Compute array meta data:
12var len = numel( shape );
13var strides = shape2strides( shape, order );
14
15// Randomly flip the sign of strides...
16var i;
17for ( i = 0; i < shape.length; i++ ) {
18    if ( randu() < 0.5 ) {
19        strides[ i ] *= -1;
20    }
21}
22
23// Compute the underlying data buffer index offset:
24var offset = strides2offset( shape, strides );
25
26// Print array info:
27console.log( 'Dims: %s', shape.join( 'x' ) );
28console.log( 'Strides: %s', strides.join( ',' ) );
29console.log( 'Offset: %d', offset );
30
31// For each underlying data buffer index, determine the corresponding index into an array view...
32var ind;
33for ( i = 0; i < len; i++ ) {
34    ind = bind2vind( shape, strides, offset, order, i, 'throw' );
35    console.log( 'buffer[%d] => view[%d]', i, ind );
36}
