I want to solve the following differential equation through Mathematica: du/dt=A*(d^2)u/dx^2 , A=const Practically, this is the diffusion equation. The boundary + initial conditions I have are: * u(t=0, -1<x<1) =0 * u(t=0, x>=1, x<=-1) =1 I cant find the way to input these initial/boundary conditions in a command. Any ideas? Thanks in advance!
