Detailed Description

class DtBaseTableFunction:

DtBaseTableFunction holds a base class for table functions. The domain is an arbitrary number of real values and the range is a single real value. The state includes the dimension of the function domain, and a pointer to an array of the number of data entries along each dimension. It is a virtual class, and the pure virtual functions are lookup functions for a domain point and an integrate function to find the integral over a subset of the domain.
