% @deftypefn {Function File} {} deconv (@var{y}, @var{a})
% Deconvolve two vectors.
%
% @code{[b, r] = deconv (y, a)} solves for @var{b} and @var{r} such that
% @code{y = conv (a, b) + r}.
%
% If @var{y} and @var{a} are polynomial coefficient vectors, @var{b} will
% contain the coefficients of the polynomial quotient and @var{r} will be
% a remainder polynomial of lowest order.
