NAME

Math::Interpolator::Linear - lazy linear interpolation

SYNOPSIS

        use Math::Interpolator::Linear;

        $ipl = Math::Interpolator::Linear->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 linear interpolation. See Math::Interpolator for the interface.

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.

METHODS

$ipl->y(X)

$ipl->x(Y)

These methods are part of the standard Math::Interpolator interface.
