`MULT`,*result, mat1, mat2*,[*fac1*],[*fac2*]

calculates *result = fac2 * result + fac1 * mat1 mat2*

The strings *result* , *mat1* , *mat2* are the internal names of the matrices.
If *fac1* is not given, *fac1=1* is assumed. If *fac2* is not given,
*fac2=0* is assumed. If a backquote (`) is appended to *mat1* or *mat2*
the corresponding matrix is transposed before the operation. If a backquote is appended
to *result*, the resulting matrix is transposed.
