Uniqueness of and numerical techniques for the
inverse Sturm-Liouville problem with eigenparameter dependent boundary conditions will be
discussed. We will use a Gel’fand-Levitan technique
to show that the potential $q$ in
$$-u''+qu=\lambda u,
0<x<1, u(0)=0, (a\lambda +b)u(1)= (c\lambda
+d)u'(1)$$
can be uniquely determined
using spectral data. In the presence of finite spectral data, q can be
reconstructed using a successive approximation method that involves solving a
hyperbolic boundary value problem that arises in the Gel’fand-Levitan
analysis. We also consider a shooting method where the right endpoint boundary
condition is used in conjunction with a quasi-Newton scheme to recover the
unknown potential, q.
