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...
