Generates (dense) matrices that have a given set of eigenvalues

Solves the ``inverse eigenvalue problem'' which is to generate a real-valued matrix that has the specified real eigenvalue spectrum. It can generate infinitely many dense matrices, symmetric or asymmetric, with the given set of eigenvalues. Algorithm can also generate stochastic and doubly stochastic matrices.
