This program calculates the scattering cross section of a PEC sphere that is surrounded by a dielectric shell. Diameters of the spheres and relative permitivities of the materials can be chosen by the user. The program uses matlab intern spherical bessel functions for the costly computations.

This function obtains a unitary matrix Q such that: d=diag(Q *diag(lmd)*Q). In other words, it gives a way to generate a matrix with given eigenvalues and diagonal elements.
