Defining and perform matrix/array calculations in COMSOL

Dear all,

Does anyone know if it is possible to define matrices/arrays as input parameters and perform simple evaluations such as obtaining the Trace of the matrix, conjugate transpose or matrix multiplications in COMSOL? Right now the way I see it is that I can only do it via Matlab and feed the results back into COMSOl via livelink, which i am still learning. I have created a Physics model via the PDE module which require input from the results of matrix calculations. I am still relatively new to COMSOL so any help would be appreciated!

Thanks!
Matt
