Course detail
Vector and Matrix Algebra
FEKT-BPC-VMPAcad. year: 2024/2025
In the part of vector calculus, attention is focused on vector spaces, basic concepts, linear combinations of vectors, linear dependence, independence of vectors, bases, dimensions of vector space. The introduction of a scalar product makes it possible to explain the orthogonalization of vectors and to search for the orthogonal projection of a vector on a subspace and to apply this knowledge to the solution of predetermined systems and the least squares method. In the part of matrix calculus, students are introduced to matrix algebra, eigenvalues and eigenvectors are studied and their use to diagnose matrices and calculate matrix functions and their applications. Furthermore, the positive-definite of matrices is studied.
The part of numerical methods discusses the solution of nonlinear equations and matrix systems of linear equations, approximation of functions using an interpolation polynomial, spline and least squares method, numerical derivation and integration.
