Variable density in heat diffusion equation

Suppose I have a heat diffusion equation:
rho(x)*c(x)*dT/dt=d/dx(k(x)*dT/dx)
Where rho(x) is the density, c(x) is the heat capacity and k(x) is thermal diffusivity, all being position dependent. Would I need to specify these as vectors in pdepe instead of simple numbers?

FF=[a_1*k_var; epsilon_var; c_1*D_var].*DuDx;
instead of
FF=[a_1*k_var; epsilon; c_1*D_var].*DuDx;
Best wishes
Torsten.
