Hello,

I am trying to solve a system of 4 parabolic PDE's. Some of the coefficients depend on u (nonlinear) and i need to account for this. I have tried to create a separate file that computes c in the "parabolic" command, but i'm not sure that the file can accept u as an input parameter. Does it?

If this is possible, I'm not sure how to output c. In the help, c must be the same size as x or y, but this doesn't make sense. I would think that i would need to output a tensor, which has the size: (size(x)xNxNx2x2. Can you provide additional guidence on the output of c, if possible.

Thank you,

Josh
