Anyone please help me with this problem. I only know some basic when it comes to matlab and having lots of difficulties trying to code this matrix problem Ax=b that have unknown in both A and b.
The linear system obtained in the form of
where are constants, m is time step, , (initial and boundary values – W at t=0 and W at the last node and outside =0)
How to create the tridiagonal matrix A and vector b in matalb please? I tried to search similiar codes but only found the equations where A and b are known…in this case A and b have symbolic arguments in power form and they are related to the solution
