Numerical Analysis and Optimization

Objectives

At the end of this course the student will have acquired knowledge and skills that will enable him:

(i) to approximate the solution of ill-conditioned linear systems;

(ii) to approximate the first and higher order derivatives of a function;

(iii) to approximate the solution of initial value problems;

(iv) to numerically solve some unconstrained nonlinear optimization problems.

Furthermore,the student should be able to implement, using a computational language, the algorithms related with the covered numerical methods and analyze the numerical results obtained.
