◆ operator()() [2/3]

template<class F >

void concepts::Multiple< F >::operator()	(	const Function< c_type > &	fncY,
		Function< c_type > &	fncX
	)

inlinevirtual

Application operator for complex function fncY.

Computes fncX = A(fncY) where A is this operator. fncX becomes complex.

In derived classes its enough to implement the operator() for complex Operator's. If a real counterpart is not implemented, the function fncY is splitted into real and imaginary part and the application operator for real functions is called for each. Then the result is combined.

If in a derived class the operator() for complex Operator's is not implemented, a exception is thrown from here.

Reimplemented from concepts::Operator< F >.
