In COMSOL, how can I enter a matrix variable as a coefficient in the coefficient form PDE interface?

Please login with a confirmed email address before reporting spam

I am using coefficient form PDE and the coefficients in the equation are in the matrix form(e.g. ea, da, c, etc). However, I don't konw how to enter a matrix in the coefficient form PDE interface. The matrixs are undefined variables that can't be used in this interface. So how can I enter a matrix variable as a coefficient in the coefficient form PDE interface? Thanks for your help!
