Objectives

The student must be able to apply numerical methods for mathematical problems, such as, non linear equations, approximation of functions, integration, systems of equations and ordinary differential equations.

The student must also be able to implement computational algorithms in order to solve the aforementioned problems.

Prerequisites

Students must have basic knowledge in mathematical analysis (AMI) and linear algebra (ALGA).
