LATSQR: computes a blocked Tall-Skinny QR factorization of a complex M-by-N matrix A for M >= N: A = Q * ( R ), ( 0 ) where: Q is a M-by-M orthogonal matrix, stored on exit in an implicit form in the elements below the diagonal of the array A and in the elements of the array T; R is an upper-triangular N-by-N matrix, stored on exit in the elements on and above the diagonal of the array A. 0 is a (M-N)-by-N zero matrix, and is not stored.
