Solve parabolic PDE problem

Parabolic equation solver

Solves PDE problems of the type

$$d\frac{\partial u}{\partial t}-\nabla \cdot \left(c\nabla u\right)+au=f$$

on a 2-D or 3-D region Ω, or the system PDE problem

$$d\frac{\partial u}{\partial t}-\nabla \cdot \left(c\otimes \nabla u\right)+au=f$$

The variables *c*, *a*, *f*,
and *d* can depend on position, time, and the solution *u* and
its gradient.

`parabolic`

is not recommended. Use `solvepde`

instead.

and with initial value `u0`

. The variables *c*, *a*, *f*,
