If you don’t have a Matlab station to play with, then you may try Octave.
Octave is a nice free alternative to Matlab that permits scientists to process data or to use it as a general purpose (graphic) calculator. In some cases Octave’s syntax is slightly different from Matlabs’ but standard functions such as the creation of matrices, concatenation of matrices, 2D and 3D plots, data interpolation and numerical differentiation and integration are exactly the same.
