Method Detail

getParameterValues

public double[] getParameterValues()

Specified by:

getParameterValues in class Basic1DFunction

getIncludedInFit

public boolean[] getIncludedInFit()

getDerivatives

public double[] getDerivatives(double x,
                               double[] a)
                        throws FunctionValueUndefined

Description copied from class: Fittable1DFunction

Calculates the partial derivative of the function with respect to each parameter at point x. This is a non-analytical calculation which can be overriden by subclasses which wish to provide an analytical calculation

Overrides:

getDerivatives in class Fittable1DFunction

Throws:

FunctionValueUndefined - if the function is not defined for x

valueAt

public double valueAt(double x,
                      double[] a)
               throws FunctionValueUndefined

Specified by:

valueAt in class Fittable1DFunction

FunctionValueUndefined

setFit

public void setFit(Fitter f,
                   double[] a)
            throws InvalidFunctionParameter

Specified by:

setFit in class Fittable1DFunction

InvalidFunctionParameter

getParameterNames

public String[] getParameterNames()

Specified by:

getParameterNames in class Basic1DFunction

getTitle

public String getTitle()

Specified by:

getTitle in class Basic1DFunction

setParameter

public void setParameter(int i,
                         double d)
                  throws InvalidFunctionParameter

Specified by:

setParameter in class Fittable1DFunction
