NAME

       PDL::Filter::Linear - linear filtering for PDL

SYNOPSIS

               $a = new PDL::Filter::Linear(
                       {Weights => $v,
                        Point => 10});

               $b = new PDL::Filter::Gaussian(15,2); # 15 points, 2 std devn.

               ($pred,$corrslic) = $a->predict($dat);

DESCRIPTION

       A wrapper for generic linear filters.  Just for convenience. This should in the future use
       DataPresenter.

       Also, this class should at some point learn to do FFT whenever it is useful.
