The FORTRAN level-3 BLAS call for this operation is
Here is replaced by S, D, C, or Z to indicate the datatype of the data (single, double, complex, double precision complex). Parameters TRANSA and TRANSB indicate if A and/or B are to be (conjugate) transposed in the operation and can take on values "No transpose", "Transpose", or "Conjugate transpose". Parameters M, N, and K hold the matrix dimensions m , n , and k , respectively. Parameters ALPHA and BETA hold the scaling factors and . Parameters A, B, and C equal the addresses of where the matrices A , B , and C start in memory. The leading dimensions of the matrices are given in LDA, LDB, and LDC.
