         Definition (Matrix)
         Amatrix is a rectangular array of numbers or symbols. It can be written as
                  a11 a12 ··· a1n
                  a21 a22 ··· a2n
                                                    
                   .           .      .         .   
                   .           .       ..       .   
                       .        .                .

              • We denote this array by a single letter A or by (aij) and
              • we say that A has m rows and n columns, or that it is an m × n matrix.
              • The size of A is m × n.
              • The number a is called the (i,j) entry or scalar.

                                                                                                                                                                                              4
