@stdlib/ndarray-dtype v0.2.1
dtype
Installation
npm install @stdlib/ndarray-dtype
Usage
var dtype = require( '@stdlib/ndarray-dtype' );
dtype( x )
Returns the data type of a provided ndarray.
var zeros = require( '@stdlib/ndarray-zeros' );
var x = zeros( [ 3, 2, 3 ], {
'dtype': 'float64'
});
// returns <ndarray>
var dt = dtype( x );
// returns 'float64'
Examples
var zeros = require( '@stdlib/ndarray-zeros' );
var slice = require( '@stdlib/ndarray-slice' );
var E = require( '@stdlib/slice-multi' );
var S = require( '@stdlib/slice-ctor' );
var dtype = require( '@stdlib/ndarray-dtype' );
// Create an array:
var x = zeros( [ 10, 10, 10, 10 ] );
// returns <ndarray>
// Define some slices:
var slices = [
// :,:,:,:
E( null, null, null, null ),
// 5:10,4,2:4,::-1
E( S( 5, 10 ), 4, S( 2, 4 ), S( null, null, -1 ) ),
// :,:,2,:
E( null, null, 2, null ),
// 1,2,3,:
E( 1, 2, 3, null ),
// 1,3,::2,4::2
E( 1, 3, S( null, null, 2 ), S( 4, null, 2 ) )
];
// Determine the data type for each slice...
var s;
var i;
for ( i = 0; i < slices.length; i++ ) {
s = slice( x, slices[ i ] );
console.log( '%s => %s', s.dtype, dtype( s ) );
}
