# m_determinant

It can calculate a determinant, a special number that can be calculated from a square matrix.

**Since:** 2.4

## Parameters

- `m` : A square matrix.

## Examples

    use <matrix/m_determinant.scad>

    assert(
        m_determinant([
            [3, 8],
            [4, 6]
        ]) == -14
    );

    assert(
        m_determinant([
            [6,  1, 1],
            [4, -2, 5],
            [2,  8, 7]
        ]) == -306
    );

    assert(
        m_determinant([
            [0,  4, 0, -3],
            [1,  1, 5,  2],
            [1, -2, 0,  6],
            [3,  0, 0,  1]
        ]) == -250
