Dear Tom Clemo:

Thanks for your reply!, Sorry for the late reply I am on vacation for
few months. Yeah, after I post this message I have reviewed few of
the programming language, ex C++, MATLAB, and FORTRAN to choose one
to study. I thought MATLAB is good and I can understand it easily,
because I know the mathematics, the matrix operation and found it
easy for me. I am also attending C++ class and will see which one to
use, I more inclined to use MATLAB,
Regarding the cost no problem, I can get the programme for free, I am
working in a university that is not a problem ,

Thanks again for your advice,

AB
