Luna::determinant

f32 determinant(const Float3x3 &mat)

Computes the determinant of the specified matrix.

This function performs the following operations:

return
    mat.r[0].x * (mat.r[1].y * mat.r[2].z - mat.r[1].z * mat.r[2].y) +
    mat.r[0].y * (mat.r[1].z * mat.r[2].x - mat.r[1].x * mat.r[2].z) +
    mat.r[0].z * (mat.r[1].x * mat.r[2].y - mat.r[1].y * mat.r[2].x);

Parameters

• in mat

  The matrix to compute.

Return value

Returns the computed determinant.
