Math::Interpolator::Robust - lazy robust interpolation

NAME

Math::Interpolator::Robust - lazy robust interpolation

SYNOPSIS

        use Math::Interpolator::Robust;

        $ipl = Math::Interpolator::Robust->new(@points);

        $y = $ipl->y($x);
        $x = $ipl->x($y);

DESCRIPTION

This is a subclass of the lazy interpolator class Math::Interpolator. This class implements a robust smooth interpolation. See the Math::Interpolator manpage for the interface. The algorithm is the same one implemented by robust_interpolate in the eager interpolator module Math::Interpolate.

This code is neutral as to numeric type. The coordinate values used in interpolation may be native Perl numbers, Math::BigRat objects, or possibly other types. Mixing types within a single interpolation is not recommended.

Only interior points are handled. Interpolation will be refused at the edges of the curve.
