sorting matrix in ascending order based on column 1 (and ascending order also for column 2)

Hi all, is there a way to sort A in ascending order based on column 1, allowing its other columns to follow with it

A = [1	2	5
1	3	3
2	3	12
1	4	2];

results should be:

B = [1	2	5
1	3	3
1	4	2
2	3	12  
];

Use the sortrows command.

B = sortrows(A,1);
