eigeninv (version 2011.8-1)
Generates (dense) matrices that have a given set of eigenvalues
Description
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.
