zerosLike

Create a zero-filled ndarray having the same shape and data type as a provided ndarray.

Installation

npm install @stdlib/ndarray-base-zeros-like

Usage

var zerosLike = require( '@stdlib/ndarray-base-zeros-like' );

zerosLike( x )

Creates a zero-filled ndarray having the same shape and data type as a provided ndarray.

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

var x = zeros( 'float64', [ 2, 2 ], 'row-major' );
// returns <ndarray>

var y = zerosLike( x );
// returns <ndarray>

var sh = y.shape;
// returns [ 2, 2 ]

Notes

• Along with data type, shape, and order, the function infers the "class" of the returned ndarray from the provided ndarray. For example, if provided a "base" ndarray, the function returns a base ndarray. If provided a non-base ndarray, the function returns a non-base ndarray.

Examples

var dtypes = require( '@stdlib/ndarray-dtypes' );
var zeros = require( '@stdlib/ndarray-base-zeros' );
var zerosLike = require( '@stdlib/ndarray-base-zeros-like' );

// Get a list of data types:
var dt = dtypes( 'numeric' );

// Generate zero-filled arrays...
var x;
var y;
var i;
for ( i = 0; i < dt.length; i++ ) {
    x = zeros( dt[ i ], [ 2, 2 ], 'row-major' );
    y = zerosLike( x );
    console.log( y.data );
}
