Notes on Linear Algebra

      Here are some loose notes on some of the topics we covered.  They are not comprehensive nor are they original.
        I write them sometimes as a summary or because of some points that I would like to emphasize. In any case they are
        not a replacement of the book.


                                           Basis

                                Fundamental Theorem of Linear Algebra

                                Discrete Fourier Transform

                                Determinants

                                Complex matrices
