I am at a loss on how to code these to solve in the Crank Nicolson equation. I have solved the equations, but cannot code it into matlab.

Hi Conrad, If you are trying to solve by crank Nicolson method, this is not the way to do it. You have to solve it by tri-diagonal method as there are minimum 3 unknowns for the next time step. There are many videos on YouTube which can explain this. Hope this helps. If you can post a code after doing this, we can have a look at it. Best,

Crank-Nicolson is for partial differential equations, this seems to be ordinary differential equations. Perhaps try matlabs ode23 et al.
