In case anyone else has the same problem, make sure "Interpret vector parameters as 1-D" is unchecked in the constant block if you want to do matrix multiplication.

In pravin's model, Simulink is probably reading Constant2 as size [3] instead of [1x3].

Interchange those two constant blocks. The error is occurring due to mismatch in dimension. Here you are trying to multiply matrix of size 3*3 by 1*3. But, correct multiplication will be 1*3 by 3*3.
