Prerequisites:

Numerical Analysis 
Target skills and knowledge:

Advanced knowledge of Numerical Analysis and its applications in Applied Mathematics. 
Examination methods:

Written exam (theory) and oral exam (laboratory). 
Assessment criteria:

In the written examination we understand the theoretical knowledge obtained by the student, with particular attention to the comprehension of the algorithms, their properties, and proofs of major theorems.
In the part of lab, we evaluate how much the students have programming skills as well as understanding of the performed numerical experiments. 
Course unit contents:

Interpolation.
Orthogonal polynomials.
Numerical quadrature.
Iterative methods for linear algebra.
Nonlinear systems.
Eigenvalues.
Finite differences methods for ODEs and PDEs. 
Planned learning activities and teaching methods:

Interpolation.
The general problem of interpolation, unisolvent sets and determinantal formula of Lagrange, the univariate and multivariate case, Lebesgue constant, fundamental estimate for interpolation error, stability, brief introduction to tensorial product interpolation and Fekete points.
