    Hello everybody who want to work with intdiff.
    Algorithm of getting started is simple:
    look into math paper and write down simpliest equations to solve. There is something about numerical solving in the paper, but it isn't initial level of difficulty, so try simpliest methods first, and only then modify them! There is some examples of solving simple PDE's in CVS:

    1.diffusive solves simple du/dt=D(d^2u/dx2) with Crank-Nicolson scheme (it isn't simpliest Euler scheme, but this is because...see below)

    2. pde-qlo solves simple Schroedinger eq.
    i*d(psi)/dt=D*(d^2(psi)/dx2), where i=sqrt(-1). It is generalization of diffusive (...Euler doesn't work with Schroedinger eq because it isn't unitary)

    Good coding!

    P.S. I'll join intdiff subproject when I get pde-qlo working in more difficult cases -- this is needed for my course paper.

      I'd like to join indiff project. Currently I'm a student and this problem seems to be appropriate for me.

      Very well, I've added you to the team.

      I've finished code solving Schroedinger equation for arbitrary potential function.
