ENDIF The Fortran source code for the exercises in this tutorial. This call to the Use dgemm to Multiply Matrices ELSE 1) Simplest case two square complex matrices: A (N,N) and B (N,N) and I want to store ther result in C (N,N) the call to cgemm will be SUBROUTINE CGEMM ( TRANSA, TRANSB, N, N, N, ALPHA, A, LDA, B, LDA, BETA, C, LDC ) where LDA=LDB=LDC=N and TRANSA (B) can be an operation on the matrix A (B) 'N' = use the A matrix as it is For the executables in this tutorial, the build scripts are named: This assumes that you have installed Intel MKL and set environment variables as described in.
