How to extract a column from a matrix/array in MATLAB.

To know about how to extract a column from an array or matrix in MATLAB consider the following form i.e

        variable-name=matrix-name(rows,columns)

where:  

  ?  Variable-name:

                             It  shows the place where you can name your variable in which you wanna                                  store your extracted data.

  ?  Matrix-name:

                       It shows the place where you have to place your matrix name or array name from which you                          wanna extract your desired data.

  ?              ( ):

                      we use these parenthesis to send a command to MATLAB that we are gonna tell you the                             address in terms of rows and columns of an array/matrix.

  ?          Rows:

                      It shows the place where you have to put the position of your desired row (e.g 1st row or 2nd                                           row etc) of a matrix/array that you wanna extract,.we will use : in this place  which means                          each row.

  ?      Columns:

                      It shows the place where you have to put the position of your desired column(e.g 1st column or 2nd                                 column etc) of a matrix/array that you wanna extract.
