Detailed Description

--------------— gemm ---------------— performs one of the matrix-matrix operations

\[ C := \alpha op( A ) op( B ) + \beta C, \]

where op(X) is one of

\[ op( X ) = X \mbox{ or } op( X ) = X^T, \]

\( \alpha \) and \( \beta \) are scalars, and A, B and C are matrices, with op(A) an \( m \times k \) matrix, op(B) a \( k \times n \) matrix and C an \( m \times n \)m matrix.
