Language of instruction

Czech

Mode of study

Guarantor

doc. Ing. Petr Tomášek, Ph.D.

Department

Institute of Mathematics (ÚM)

Entry knowledge

Linear algebra, vector calculus, differential and integral calculus.

Rules for evaluation and completion of the course

The exam has an oral part only. The student has to answer three questions, one question from the range "numerical linear algebra", second question from the range "solving nonlinear equations" and third question from the range "interpolation, differentiation and integration".

Attendance at lectures is recommended. Lessons are planned according to the week schedules. Absence from lessons may be compensated by the agreement with the teacher supervising the lectures.

Aims

The objective of the course is to make students familiar with numerical methods of linear algebra, with solution methods for nonlinear equations and with methods of interpolation, numerical differentiation and integration.
Students will be made familiar with basic numerical methods of linear algebra, nonlinear equations, interpolation, differentiation and integration. Based on this knowledge they ought to be able to choose suitable software product (exceptionally to write their own program) and then succesfully apply it in solving their specific technical problems.
