Course Content
Numerical applications and methods for the solution of astrophysical problems. The course will start with a recall of the basic structure of the C language together with the use of functions and structures. Numerical methods to solve linear algebraic equations, interpolation, and integration, as well as to solve ordinary differential equations will be shown. These methods will be applied in astrophysical context such as orbits and stellar structure.

Learning Objectives
The course aims to provide knowledge of some basic numerical methods to solve complex physical problems with special emphasis on astrophysical processes. At the end of the course the student will acquire ability in using such methods will improve his/her capacity to build-up algorithms for solving numerical problems.
Prerequisites
None. It is however useful to have some basic knowledge of a programming language (the C language is preferable).
