26 @majorheading GiNaC Examples
28 This is a collection of code examples using GiNaC.
32 @chapter Input / Output
34 @section Archiving expressions @uref{archive1.cpp, (source)}
36 Two expression are stored in an archive on the disk and are restored again.
38 @section Input and output of expressions
40 @subsection Expression input @uref{derivative.cpp, (source)}
42 Interactively input expression and compute its derivative with respect
43 to the ``x'' variable.
45 @chapter Monte Carlo Integration
47 @section Example showing compile_ex @uref{compile1.cpp, (source)}
49 Simple example showing compile_ex with one free variable. Timing between CLN and C double numerics is done.
51 @section Using VEGAS from CUBA @uref{compile2.cpp, (source)}
53 An expression in two variables is integrated by using VEGAS from the
54 @uref{http://www.feynarts.de/cuba/, CUBA library}.
56 @section Example showing link_ex @uref{compile3.cpp, (source)}
58 Demonstrates the use of link_ex. Program has to be called more than once to see the effect.
60 @chapter Lanczos Approximation
62 The program lanczos.cpp calculates coefficients for use in the Lanczos
63 approximation of the gamma function. The Lanczos approximation is used by
64 the function inside GiNaC that approximates the gamma function numerically.
