Here are the PDE, Initial and Boundary conditions:
I found the analytical solution using the Separation of variables method. I am trouble having finding the Numerical Solution. How can I do this in MATLAB?

By writing your equation as a system of two equations
du/dt = v
dv/dt = -d^4u/dx^4,
discretizing the spatial derivative and solving the resulting system of ordinary differential equations using ODE15S.
