isndarrayLike

Test if a value is ndarray-like.

Usage

var isndarrayLike = require( '@stdlib/assert/is-ndarray-like' );

isndarrayLike( value )

Tests if a value is ndarray-like.

var ndarray = require( '@stdlib/ndarray/ctor' );

var arr = ndarray( 'generic', [ 0, 0, 0, 0 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var bool = isndarrayLike( arr );
// returns true

A value is ndarray-like if a value is an object with the following properties:

• dtype: string specifying a data type.
• data: object pointing to an underlying data buffer.
• shape: array-like object containing dimensions.
• strides: array-like object containing stride lengths.
• offset: number specifying the index offset.
• order: string describing the memory layout.
• ndims: number specifying the number of dimensions.
• length: number specifying the total number of elements.
• flags: object containing meta data.
• get: function for retrieving elements.
• set: function for setting elements.

Examples

var ndarray = require( '@stdlib/ndarray/ctor' );
var isndarrayLike = require( '@stdlib/assert/is-ndarray-like' );

var arr = ndarray( 'generic', [ 0, 0, 0, 0 ], [ 2, 2 ], [ 2, 1 ], 0, 'row-major' );
var bool = isndarrayLike( arr );
// returns true

bool = isndarrayLike( [ 1, 2, 3, 4 ] );
// returns false

bool = isndarrayLike( {} );
// returns false

bool = isndarrayLike( null );
// returns false
