Crank-nicolson matlab

Web$\begingroup$ The Crank-Nicolson method is actually one of the two second-order temporal schemes offered by OpenFOAM for Navier-Stokes equations. The other is BDF2. For diffusion problems Crank-Nicolson is still quite popular. It used to be used in a combination with Adams-Bashforth and now more typically with Runge-Kutta.
