Documentation for the abstract class IBaseFunctionMultiDim. Interface (abstract class) for generic functions objects of multi-dimension Provides a method to evaluate the function given a vector of coordinate values, by implementing operator() (const double *). In addition it defines the interface for copying functions via the pure virtual method Clone() and the interface for getting the function dimension via the NDim() method. Derived classes must implement the pure private virtual method DoEval(const double *) for the function evaluation in addition to NDim() and Clone(). @ingroup GenFunc

Look at the header to check for available constructors.

double operator()(const double* x)

Evaluate the function at a point x[]. Use the pure virtual private method DoEval which must be implemented by the sub-classes

return DoEval(double x) const

double operator()(const Iterator it )

Template method to eveluate the function using the begin of an iterator User is responsible to provide correct size for the iterator
