I have a matrix as shown below. The first column contains identity of objects and the second and third column corresponds to there detection times. What i want to do is to keep all the elements corresponds to the identical elements in the first column together.
eg: a = [51, 1.5, 3.8; 52, 1.8, 9.6; 53, 2.1, 8.8; 51, 3.5, 9.9; 54, 8.5, 10.23,51, 1.5, 3.8 ];
Is there a way to do this rather than using for loops and conditions? Any help will be appreciated.
