Re: what do I need to study numerical analysis ?

It depends on the course, but I would suggest some understanding of elementary analysis would be useful, including some of the major results you are likely to use, e.g. contraction mapping theorem (Banach fixed point theorem), Taylor's theorem, intermediate value theorem, mean value theorem. A basic understanding of solutions to ODEs or a first course in differential equations would probably be essential, as well as standard mathematical methods of calculus. Some basic linear algebra might be useful, too (what will mainly be relevant to you are systems of equations and a few things about matrices and eigenvalues).

Programming experience (e.g. MATLAB, or your favourite mathematical computation package or programming language) would also help.
