Overview

This module contains classes and functions that are needed for numerical computations within GammaLib. The module provides support for differentiation and integration of one-dimensional functions. The interface for the one-dimensional functions is defined by the abstract GFunction base class, integration is performed using the GIntegral class, differentiation is done using the GDerivative class. In addition, numerical constants and function that are extensively used throughout GammaLib are defined in the GMath.hpp header file. All constants and functions are declared in the gammalib namespace.
