I know that this question may seem simple to some of you, but I'm wondering if MATLAB's pdepe tool can solve a coupled system of parabolic pde's? The general form is:
d(u1)/dt = d2(u1)/x2 - d2(u2)/x2 d(u2)/dt = d2(u2)/x2 - d2(u1)/x2
More specifically, how does the DuDx command work in the pdepe tool? Can I enter an array for the coefficients of the b function and will it know that the second column coefficient corresponds to u2?
Thanks in advance for your time! Jacob
