% @deftypefn {Function File} {} conv (@var{a}, @var{b})
% Convolve two vectors.
%
% @code{y = conv (a, b)} returns a vector of length equal to
% @code{length (a) + length (b) - 1}.
% If @var{a} and @var{b} are polynomial coefficient vectors, @code{conv}
% returns the coefficients of the product polynomial.
