Detailed Description

Class for multiplication of a one-dimensional function by another.

This class implements the multiplication of a generic one-dimensional function by another (both functions may be of any type of functions derived from Base1D1DFunction).

virtual

TODO: Returns the value of the derivative of the function func1 by another function func2 at the point domainValue.

Todo:
Please, implement me!
This method objective requires clarification: are we calculating either (func1*func2)' or func1'*func2'?

Returns the value of the multiplication of a function func1 by another function func2 at the point domainValue, i.e. returnValue = func1(domainValue)*func2(domainValue) .

This function calls the value() method of the both functions and multiplies their return value with one another.
