Sort rows of a matrix

Hello,

I would like to sort the rows of a matrix depending on the values of each row. So i sould sort the rows based on the first entry of the row, and then i would sort what i have based on the second row and so on. Here is an example, consider the following matrix

A =

     1     2     3
     1     2     4
     3     1     2
     1     1     1

The output should be the following

     A =

     1     1     1
     1     2     3
     1     2     4
     3     1     2
