scalar
k ⨉ k matrix, where k is n when Right flag is set and is m otherwise.
m ⨉ n matrix
scalar. When beta is supplied as zero then the matrix csl need not be set on input.
m ⨉ n matrix with one stride equals to ±1.
C := alpha A × B + beta C or C := alpha B × A + beta C, where alpha and beta are scalars, A is a symmetric or hermitian matrix and B and C are m × n matrices.
Performs symmetric or hermitian matrix-matrix multiplication.
