Dear all, I am having trouble with the following problem. Suppose we have the fourth order ODE with boundary conditions:
http://r.789695.n4.nabble.com/file/n4591748/problem.jpg problem.jpg where q(t) is a known function. Note here the lambda parameter is changing, so essentially we have a series of ODEs. lambda is called an eigenvalue, the solution y is called an eigenfunction associated with lambda. The question is to find the eigenvalues lambda and eigenfunctions y. In matlab, this can be done. I am wondering if R has similar functions to achieve this goal. Any suggestions will be highly appreciated.
