Create matrix by the variants

$variants = [
    'a' => [1, 2],
    'b' => [10, 20],
];
$matrix = CreateMatrix::byVariants($variants)->getArray();

// result
$matrix = Array
(
    [0] => Array
        (
            [a] => 1
            [b] => 10
        )

    [1] => Array
        (
            [a] => 1
            [b] => 20
        )

    [2] => Array
        (
            [a] => 2
            [b] => 10
        )

    [3] => Array
        (
            [a] => 2
            [b] => 20
        )

)

Create matrix with variant an empty value

$variants = [
    'a' => [1, null],
    'b' => [10, null],
];
$matrix = CreateMatrix::byVariants($variants)->getArray();

// result
$matrix = Array
(
    [0] => Array
        (
            [a] => 1
            [b] => 10
        )

    [1] => Array
        (
            [a] => 1
            [b] => 
        )

    [2] => Array
        (
            [a] => 
            [b] => 10
        )

    [3] => Array
        (
            [a] => 
            [b] => 
        )
