Elective
3rd Cycle Studies
Recommended Prerequisites
Calculus I,II,III, Numerical analysis, Algebra, Statiscics. Fortran, C++, Pascal.
Teaching Methods
Theoretical classes with detailed exposition, making resource to audiovisual media, of the fundamental concepts, principles and theories. Resolution of some practical examples in each chapter. The classes are concentrated in some weeks of the semester. The evaluation consists on a final exam or, in alternative, in the making of some theoretical and practical works.
Learning Outcomes
This course involves the contact with mathematical and classical and advanced numerical methods. The principal aim is to provide skills for the exercise of theoretical and computational research.
