WebCGETRF computes an LU factorization of a general M-by-N matrix A using partial pivoting with row interchanges. The factorization has the form A = P * L * U where P is a permutation matrix, L is lower triangular with unit diagonal elements (lower trapezoidal if m > n), and U is upper triangular (upper trapezoidal if m < n). http://www.hpc.lsu.edu/training/weekly-materials/Past%20Tutorials/Intro-LAPACK-0309.pdf
