Convert a matrix into an upper triangular matrix


The jit.la.determinant object converts a given input matrix to an upper triangular matrix via Gaussian elimination. The input matrix must have typefloat32 or float64, and may have planecount 1 or 2. If the input matrix has a planecount of 2, it is assumed that the data is from the set of complex numbers.
