BUG FIXES. 3) Another possibility is to use operations different from N, for example the transpose T of the hermitian C, for example this two codes are equivalent but the second is faster and use less memory: notice that the LDA and LDB specify the entry dimension of the matrix A and B, therefore in the second case the entry dimension is the first dimension of the original matrices A and B, while in the first example it corresponds to the one of transpose(A) and transpose(B).
