Inheritance diagram for Unfit::Examples::ParabolaWithHole:

Public Member Functions
std::vector< double >	operator() (const std::vector< double > &variable)
Public Member Functions inherited from Unfit::GenericCostFunction
virtual	~GenericCostFunction ()

Detailed Description

This test function is a simple parabola, y=x*x, where we want to find x=0. The catch is that this one has a hole filled with NaNs around the solution.

Member Function Documentation

operator()()

std::vector<double> Unfit::Examples::ParabolaWithHole::operator() ( const std::vector< double > &  variable )

inlinevirtual

We overload the operator as is required in GenericCostFunction to calculate the cost of the function.

Parameters

variable

the current estimate of x

Returns

a vector of residuals (length one in this case)

Implements Unfit::GenericCostFunction.
