solvepde (=pde toolbox?) seem to be based on finite elements. If so what time integration (ode23 etc) is adopted?

Hi,

You are correct, the solvepde function in MATLAB's PDE Toolbox is indeed based on finite element methods. In the following documentation they have explained how it works. They mention in the last line the toolbox calls the appropriate solvers internally, once the problem is reduced to ODEs or algebraic equations. Please refer to the following documentation page for more understanding:
