Re: Sturm-Liouville Problem (differential equation eigenvalue problem)
Hi, why not ? v[x]==u[x]+va+(vb-va)*(x-x0)/(xe-x0) It changes the form of differential equationfor v[x] thats right, but it is more important to have homogen boundary conditions. You can still try other functions when the transformed differential equation becomes easyer.
