Thanks for this correction.  I fixed the documentation here (https://hg.savannah.gnu.org/hgweb/octave/rev/a4a7e887ddb0).

## Given an @var{n*n} matrix polynomial

## 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 @var{n}*@var{l}) with columns that correspond to the
