Learning outcomes of the course unit

The succesful course leaver should be able to correctly and precisely define the fundamental concepts of matrix and tensor calcullus; moreover, he or she should be able to demonstrate at least 2-3 concrete examples for each discussed concept. The course leaver should also be able to formulate the most important theorems of the matrix and tensor calcullus, including the precise formulations of their assumptions of validity. The student, passing the course should know and understand to the main principles of the proofs of the discused theorems and should be able to explain them. The successful course leaver should be able to apply the discussed notions and theorems for the solution of concrete tasks and exercises from a given class, covering the most common applications.

Prerequisites
