Need help with PDE

Need help with PDE

(OP)
Hey, guys

I need help to solve the following PDE:



I am struggling with obtaining solution such that p varies with t and x. In my solution, Matlab only show initial value of P for all t and x.

Can you please review the code I attached and suggest better ways to achieve the goal.

Thanks.

RE: Need help with PDE

Perhaps some %comments explaining what you have done will be necessary.

RE: Need help with PDE

Your code looks incomplete. For example, dss004.m doesn't define r4fdx. It looks like you've just copied it from here:

http://www.scholarpedia.org/article/Method_of_line...

anyway, so why remove all the commenting and the necessary prelim?

Sounds too suspicious to me at this stage to spend any longer on it. Will wait to hear back.
