% @deftypefn {Function File} @var{y} = downsample(@var{x},@var{n})
% Downsample the signal, selecting every nth element. If @var{x}
% is a matrix, downsample every column.
%
% For most signals you will want to use decimate instead since
% it prefilters the high frequency components of the signal and
% avoids aliasing effects.
