Does COMSOL support simple matrix operations?

The below post is related to an archived discussion

[start here]

I need to define a matrix variable M as an expression of matrix products. For example, M = A * B. A and B are known. One certainly can find the elements of M analytically by hand or through LiveLink with Matlab. However, I would like to know whether it is possible to do this within COMSOL only, that is, the definition of M as A * B directly.

Thanks!
