Description:

The TTable class is used to generate a lookup table to approximate a function g(x).

The source code:

table.h
table.cc

Usage:

#include "table.h"

double g(double x);
TVector v(1000);

TTable t( g, -1.0, 1.0, 1000 );

Creates a lookup table t that approximates the function g. The function g is sampled 1000 times within the interval [-1.0, 1.0] to generate the table.

TTable t( v, -1.0, 1.0);

Creates a lookup table t that approximates a function in the range [-1.0, 1.0]. The TVector v contains equally spaced samples of the function to be approximated within the specified range.

TTable(is);

Creates a lookup table and reads the table from the istream is
