Member Function Documentation

Function()

virtual real_t Function ( const Vect< real_t > &  x, int  i = 1  )

pure virtual

Virtual member function to define nonlinear function to zeroe.

Parameters

[in]	x	Vector of variables
[in]	i	component of function to define [Default: 1].

Returns

Value of function

Warning

The component must not be larger than vector size

Gradient()

virtual

Virtual member function to define partial derivatives of function.

Parameters

[in]	x	Vector of variables
[in]	i	Function component [Default: 1]
[in]	j	Index of partial derivative [Default: 1]

Returns

Value of partial derivative
