Modeling a pde on matlab

How do I model the given pde on matlab

At first, you need a second differential equation because the one above has P and H as unknowns.
H is known

You can use the "pdepe" function in MATLAB to solve initial-boundary value problems for systems of PDEs in one spatial variable x and time t.
You can learn more about its usage from the link below,
The following page also has some examples of solving PDEs that you can refer,

Hi N G, you can check out the example on this page, which explains how to use a spatial mesh and plot the solution to model a partial differential equation:
Hope this helps!

So you have H as a function of x and t. Are you sure about the + sign between the derivatives on the right-hand side ? Then
should be a good starting point.
Or use the PDE toolbox.
