DP = dot_product(A,B)

`The meaning is
`

`For two matrices C and D (at least one has dimension 2) their
matrix-matrix product is given by
`

E = matmul(C,D)

`The result is a matrix. The shapes of C, D, E have to
obey the usual mathematical relation for matrix multiplication.
Note that the matrix product
MATMUL(C,D) is not equal to the element-by-element product C*D.
