Classes
interface	IG::Num::IFunc2d
	Represents scalar functions of 2 variables. More...
class	IG::Num::Func2dBaseNoHessian
	Base class for scalar functions of 2 variables (implementations of the IFunc2d interface). that do not implement calculation of the Hessian (second derivatives). Beside the IFunc2dinterface, this class also implements the IScalarFunctioninterface. This does not affect efficiency but adds the functionality for using objects as general (untransformed) scalar functions. More...
class	IG::Num::Func2dBaseNoGradient
	Base class for scalar functions of 2 variables (implementations of the IFunc2d interface). that do not implement calculation of function Hessian (second derivatives) or gradient. Beside the IFunc2dinterface, this class also implements the IScalarFunctioninterface. This does not affect efficiency but adds the functionality for using objects as general (untransformed) scalar functions. More...
class	IG::Num::Func2dBase
	Base class for scalar functions of 2 variables (base for implementation of IFunc2d interface). Beside the IFunc2dinterface, this class also implements the IScalarFunctioninterface. This does not affect efficiency but adds the functionality for using objects as general (untransformed) scalar functions. More...
class	IG::Num::Func2dVectorFormBase
	Base class for scalar functions of 2 variables (base for implementation of IFunc2d interface). Derive from this class when your basic implementations of evaluation methods are in vector form (parameters as vec2 struct).Beside the IFunc2d interface, this class also implements the IScalarFunction interface. This does not affect efficiency but adds the functionality for using objects as general (untransformed) scalar functions. More...
class	IG::Num::Func2dLinear
	Linear (Affine) function of 2 variables. Function is evaluated according to fl(x) = b^T*x + c where x is vector of parameters, b is the vector of linear coefficients (gradient at x=0) and c is the scalar term (function value at x=0). More...
class	IG::Num::Func2dQuadratic
	Quadratic function of 2 variables. Function is evaluated according to q(x) = (1/2)*x^T*G*x + b^T*x + c where x is vector of parameters, G is constant Hessian matrix, b is the vector of linear coefficients (gradient at x=0) and c is the scalar term (function value at x=0). More...
class	IG::Num::Func2dExamples
	Example classes of type Func2d. More...
class	IG::Num::Func2dExamples::Func2dXY
	Function f(x, y) = x * y. Value and gradient are defined. More...
class	IG::Num::Func2dBasePlain_ToConsider
	Base class for scalar functions of 2 variables. This willl be base class for most of other classes that implement the IFunc2d interface. It provides a set of useful static methods. More...
