# PDL::Linear(3pm)

linear filtering for PDL

## NAME

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

## SYNOPSIS

```
        $x = PDL::Filter::Linear->new(
                {Weights => $v,
                 Point => 10});
        $y = PDL::Filter::Gaussian->new(15,2); # 15 points, 2 std devn.
        ($pred,$corrslic) = $x->predict($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.
