You have to do C++ Programming when doing business and math? 
Thats some intense course!
i used to do some basic stuff, nothign to complex post your problem here and ill see if i can help
What I need is a program solving the linear system Av=r.
A is a tridiagonal matrix with vector a(nx1) as the main diagonal and vector b(n-1x1) as the upper and lower bidiagonal.
the user can choose n rows in the system
then enter the elements in vector a, b and r and the program should create A|r and print this to a datafile.
this would be a great help if you could figure this out.
i could write the program but i cant work out the equation for the maths :/ writing a consol application to do maths is one of the easiest things to do in c++ but i wouldnt have a clue what equation to get it to work out, give yourself a few weeks and you could easily learn enough c++ to do that
thanks for the advice.
