To handle matrices I use DynMatrix http://paginas.fe.up.pt/~paco/pmwiki/index.php?n=DynMatrix.DynMatrix > > 2. display graphic representations of data (ploting functions or points > in coordinate system, contour plots, 3D plots, etc; example here again > my be python multiplot package)?

Lazarus has TAChart component for 2D graphs http://wiki.lazarus.freepascal.org/TAChart I've used GLScene for some 3D plotting http://wiki.lazarus.freepascal.org/GLScene You should try the Lazarus mailing list for extra help.
