The course is devoted to the most widely used Krylov subspace iterative methods for solving systems of linear algebraic equations, linear approximation problems and eigenvalue problems. The emphasis is put especially on effective algorithmic realization and convergence analysis. The course extends some topics discussed in the course Analysis of Matrix Calculations 1 (NMNM331).

Last update: Stefano Pozza, Dr., Ph.D. (23.04.2020)

To finish the course successfully, it is required to pass the exam covering all presented topics, see "Requirements to the exam".

Furthermore, students will complete one homework assignments during the semester. The homework consists of implementing a selected method in the MATLAB environment.

Last update: doc. RNDr. Iveta Hnětynková, Ph.D. (07.04.2015)

Lectures are held in a lecture hall, practicals in a computer laboratory (Matlab enviroment).

Requirements to the exam -
Last update: Stefano Pozza, Dr., Ph.D. (23.04.2020)

The exam reflects all the material presented on lectures and practicals during the whole semester. The exam has oral form.

It is probable that a large part of the exams or credits could take place in a distance form. It depends on a development of the situation and we will inform you about the changes immediately.
