The @MTXMUL function multiplies matrix B by matrix C and places the result in matrix A.   Syntax for @MTXMUL is:

A = @MTXMUL( B, C);

The matrices must all be defined on dense sets.  The dimensions of the matrices must also agree, for example, if B is an m x n matrix, then C must be an n x p, and A must be an m x p matrix.  Furthermore, m, n and p must be greater than 1, i.e., inner and outer products are not currently allowed.  @MTXMUL may only be used in calc sections, and may not appear in the optimizable model sections.
