## Given an @var{n*n} matrix polynomial
##
## @address@hidden(s) = @var{C0} + @var{C1} s + @dots{} + @var{Cl} s^l}
##
## @code{polyeig} solves the eigenvalue problem
##
-## @code{(@var{C0} + @var{C1} + @dots{} + @var{Cl})v = 0}.
+## @code{(@var{C0} + @var{C1} z + @dots{} + @var{Cl} z^l) v = 0}.
##
## Note that the eigenvalues @var{z} are the zeros of the matrix polynomial.
## @var{z} is a row vector with @var{n*l} elements.  @var{v} is a matrix
## (@var{n} x @address@hidden) with columns that correspond to the
## eigenvectors.
