Detailed Description

template<class T>
class casacore::MathFunc< T >

A class to generate values of mathematical functions.

Synopsis

This class is the abstract base class for 1-dimensional math functions.

Actual math functions are then an inherited class from the base class. This approach allows one to define actual function values for each derived class. Then, one can pass a generic MathFunc pointer to other objects, but the other objects will still get function values from the actual inherited function.

By defining each math function as an object, we can place parameters which will not change from one call to the function value to another in the class definition and they only have to be initialized once.

MathFunc is the base class for 1-dimensional math functions
