Class PolynomialFitter.ParameterBounds

java.lang.Object

edu.cnu.mdi.splot.fit.PolynomialFitter.ParameterBounds

Enclosing class:

PolynomialFitter

public static final class PolynomialFitter.ParameterBounds
extends Object

Coefficient bounds for c0..cN. Use +/-infinity for "no bound".

This is retained as a polynomial-friendly API, but the actual enforcement is handled through the base class ParameterValidator mechanism (via clamping).
