INTRODUCTION TO MATRICES IN MATLAB

Basics of Matrices Row Matrix  :

row matrix:

a matrix which has only one row.
 example:  [1  2  3]

 column Matrix :

 a matrix which has only one column
 example    [ 1
                      2
                      3 ]

 square matrix:

has equal number of rows and columns

 ex: a=[  2      2
               4     4   ]

 this a 2 x 2 matrix rectangular matrix: matrix which has unequal columns and rows

 ex: a = [2  2  2
              4  4  4 ]

 coding for initializing the each of the above matrices: 

row matrix initializing

a = [1  2  3]                                 (this initilizes a row matrix)

column matrix initializing:

b = [1 ; 2 ; 3]                          (';' is used to end a particular row)

square matrix initializing:

c = [2   2   ;  4   4]

rectangular matrix initializing:

d = [2   2   2 ; 4   4   4]

the output is
