jit.la.uppertri 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 type float32 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.	from the library : Jitter Format : External Environment : jitter commercial Max 4.x http://www.cycling74.com
