Learning Outcomes

The goal of the course is to introduce the basic fundamental ideas and techniques of Linear Algebra, ideas the students will meet in many other basic and advanced courses .The course begins with the algebra of matrices and vectors and then considers methods of solution of Linear systems (some of them are produced by the modeling of physical phenomena).The notions of the inverse and the determinant of a matrix are presented. The notion of vector space (and subspace) is introduced and we learn how these notions are related to linear systems. The notions of linear independents, basis and dimension are defined. We discuss complemented subspaces, and how to find projections onto them. The notions of eigenvalue and eigenvector is introduced. We study the diagonalization of a matrix and the method of least squares

The last section contains the basic recursive methods of solution of linear systems.

 With the successful completeness of the course the student is in a position  to:

  • Recognize notions, properties and operations with vectors  and matrices. Determine in which class belong certain matrices(square, non-square, symmetric, orthogonal, positive definite, invertible  etc.)
  • Understand the basic notions of linear independence of vectors, the concept of basis and the linear hull of a set of vectors.
  • Solve singular or non-singular linear systems with the elimination methods/algorithms.
  • Apply basic techniques of linear algebra in order to find the inverse of a matrix.
  • Calculate the null space, the column space and the line space and the rank of a matrix  and to relate them with linear systems of equations.
  • Calculate the determinant of a square matrix,  the characteristic polynomial, the eigenvalues and the eigenvectors of it, and in case this can be done to be able to find the diagonal form of a matrix.
  • Apply the  Gram-Schmidt orthonormalization and orthonormalize the basis of a vector space of finite dimension.   .
  • Recognize projections and complemented subspaces in spaces of finite dimension
  • .Use ,  Cramer’s law, the nethod of least squares, simple Markov chains
