zeros

Create a zero-filled ndarray having a specified shape and data type.

Usage

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

zeros( dtype, shape, order )

Creates a zero-filled ndarray having a specified shape and numeric data type.

var getShape = require( '@stdlib/ndarray/shape' );
var getDType = require( '@stdlib/ndarray/dtype' );

var arr = zeros( 'float64', [ 2, 2 ], 'row-major' );
// returns <ndarray>[ [ 0.0, 0.0 ], [ 0.0, 0.0 ] ]

var sh = getShape( arr );
// returns [ 2, 2 ]

var dt = String( getDType( arr ) );
// returns 'float64'

The function accepts the following arguments:

  • dtype: underlying data type. Must be a numeric or "generic" data type.
  • shape: array shape.
  • order: specifies whether an ndarray is 'row-major' (C-style) or 'column-major' (Fortran-style).

Examples

var dtypes = require( '@stdlib/ndarray/dtypes' );
var ndarray2array = require( '@stdlib/ndarray/to-array' );
var zeros = require( '@stdlib/ndarray/base/zeros' );

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

// Generate zero-filled arrays...
var arr;
var i;
for ( i = 0; i < dt.length; i++ ) {
    arr = zeros( dt[ i ], [ 2, 2 ], 'row-major' );
    console.log( ndarray2array( arr ) );
}
