Zgeru() Sub Zgeru ( M As  Long, N As  Long, Alpha As  Complex, X_I As  Complex, Y_I As  Complex, A_IJ As  Complex, LdA As  Long, Optional IncX As  Long = 1, Optional IncY As  Long = 1  ) Rank 1 operation: A <- αxyT + A (complex matrices) (BLAS 2) Purpose This routine performs the rank 1 operation A <- αxy^T + A where α is a scalar, x is an m element vector, y is an n element vector and A is an m x n matrix. Parameters [in] M Number of rows of the matrix A. (M >= 0) (If M = 0, returns without computation) [in] N Number of columns of the matrix A. (N >= 0) (If N = 0, returns without computation) [in] Alpha Scalar α. [in] X_I An element X(I) of the array X(). Starting from this location, M vector x is stored with element spacing IncX. [in] Y_I An element Y(I) of the array Y(). Starting from this location, N vector y is stored with element spacing IncY. [in,out] A_IJ An element A(I, J) of the array A(). [in] Starting from this location, M x N matrix A is stored. [out] Starting from this location, M x N matrix αxy^T + A is stored. [in] LdA Leading dimension of the two dimensional array A(). (LdA >= max(1, M)) [in] IncX (Optional) Element spacing of vector x in the array X(). (IncX <> 0) (default = 1) [in] IncY (Optional) Element spacing of vector y in the array Y(). (IncY <> 0) (default = 1) Reference BLAS
