This page presents MatLab functions for drawing the surface plots
using directly the monthly data files saved by SIGMA.
In the present moment, three documents are available:

• a brief instruction,
• a program for MatLAB version 6
• a program for MatLAB version 7

The version 7 enables better quality of plots when compared with the version 6.
NB: a name of a saved program file have extra extension .txt
that should be deleted before using a file as a MatLab function.
