| 2014-12-27 09:57:29 -0600 | asked a question | How can I sort the matrix acc. to the first column? I have a Mat. I want to change the order of its rows, based on the value of their first element. So a row that begins with 1 will be placed before a row beginning with 2 etc. If two rows begin with the same number, I want to keep their original order. Is there a simple way to achieve this ? I would be very grateful if someone help me. |
