*MULT
*MULT, M1, T1, M2, T2, M3 
Performs the matrix multiplication M3 =
    M1(T1)*M2(T2).
Argument Descriptions
- M1
- Name of matrix - M1. Must have been previously specified by a *DMAT or *SMAT command.
- T1
- Transpose key. Set - T1= TRANS to use the non-conjugate transpose of- M1. Set- T1= CTRANS to use the conjugate transpose of- M1. CTRANS is only applicable when the- M1matrix is complex. If blank, transpose will not be used.
- M2
- Name of matrix - M2. Must have been previously specified by a *DMAT command.
- T2
- Transpose key. Set - T2= TRANS to use the non-conjugate transpose of- M2. Set- T2= CTRANS to use the conjugate transpose of- M2. CTRANS is only applicable when the- M2matrix is complex. If blank, transpose will not be used.
- M3
- Name of resulting matrix, - M3. Must be specified.
Notes
The matrices must be dimensionally consistent such that the number of
columns of M1 (or the transposed matrix, if requested)
is equal to the number of rows of M2 (or the transposed
matrix, if requested). 
You cannot multiply two sparse matrices with this command (that is, M1 and M2 cannot
both be sparse). The resulting matrix, M3, will
always be a dense matrix, no matter what combination of input matrices is
used (dense*sparse, sparse*dense, or dense*dense).
