Examples

Example 1

use \NDArray as nd;

$c = nd::divide([5, 2, -3], [4, 3, 2]);

print_r($c);

[1.25, 0.666667, -1.5]

Example 2

use \NDArray as nd;

$a = new nd([[1, 2], [3, 4]]);
$b = new nd([[1, 2], [3, 4]]);

$c = nd::divide($a, $b);

print_r($c);

[[1, 1],
 [1, 1]]

Example 3

use \NDArray as nd;

$a = new nd([[1, 2], [3, 4]]);
$b = new nd([[1, 2], [3, 4]]);

$c = $a / $b;

print_r($c);

[[1, 1],
 [1, 1]]
