Rewrite the description of the PDE with LaTeX.

@NasserM.Abbasi I test the PDE by plugging in the exact solution, it turns out to be correct. And, I don't know much about the discretization, but, can backfoward FD together with central FD solve it? If so, to get u[i,j], we need u[i-1,j], u[i+1, j], u[i,j-1]: at least one unknown value is left, causing an endless loop. (It may stops for some unexpected assignments, which I think have happened in your and PlatoManiac's code, see my comment under PlatoManiac's answer for more details. ) BTW, if you just want to numerically solve it, NDSolve is enough.
