 function y = polyvalm (c, x)
 
-# usage: polyvalm (c, x)
-#
-# Evaluate a polynomial in the matrix sense.
-#
-# In octave, a polynomial is represented by it's coefficients (arranged
-# in descending order). For example a vector c of length n+1 corresponds
-# to the following nth order polynomial
-#
-#   p(x) = c(1) x^n + ... + c(n) x + c(n+1).
-#
-# polyvalm(c,X) will evaluate the polynomial in the matrix sense, i.e. matrix
-# multiplication is used instead of element by element multiplication as is
-# used in polyval.
-#
-# X must be a square matrix.
-#
-# SEE ALSO: polyval, poly, roots, conv, deconv, residue, filter,
