Applications to quadratic forms on the problems min-max of a function of several real variables.
Course objectives

Since the topic of the course is the study of fundamental concepts of the linear algebra such as vector spaces and linear transformation, the matrix theory is an essential tool in the study and modeling of many mathematical problems and the concept of the matrix is unfamiliar to the student, the main aim of the course is:

  • to familiarize students with the concept of the matrix, to present the basic methods of solving linear systems, to study the basic and characteristic properties of the square matrices,
  • the development of computational methods and techniques for the calculation of various sizes, and
  • the theoretical study of properties of topics, such as vector spaces.

The course aims at the acquisition of knowledge and skills so that they can be applied to other courses of mathematics and computer science.
