Experiment with
• pseudocode in MC
surface = main programm
user-function = subprogramm
• functions in C / C++
MC library with DLLs

Pseudocode with 10 operators
• programm = function with
return values (scalars,
vectors, matrices or strings)
• most common control
structures
• error messages

MC programm function becomes
necessary and helpful, especially
• in comparison of different
approximate methods
• finding approximate solutions
of non-linear equations
• define composite functions

Functions in C / C++
you need:
• MC specific data types
• special features and routines
to generate DLLs
• visual studio or another IDE
