n*M.M ( alpha A B -- alpha*A.B )
Basic Linear Algebra Subroutines (BLAS) interface » BLAS interface matrix operations

Prev:	n*M.M+n*M ( alpha A B beta C -- alpha*A.B+beta*C )
Next:	M. ( A B -- A.B )

Vocabulary
math.blas.matrices

Inputs

alpha	a number
A	a blas-matrix-base
B	a blas-matrix-base

Outputs

alpha*A.B

a blas-matrix-base

Word description
Calculate the matrix product αAB and return a freshly allocated matrix containing the result. The width of A and the height of B must match. The returned matrix's height will be the same as A's, and its width will match B's. Corresponds to the xGEMM routines in BLAS.
