Help: sort a m by n matrix
1 view (last 30 days)
I have a 4 by 2 matrix. c=[2205 300; 7281 300; 3535 600; 5944 600] and want to sort the 1st colum and the 2nd colum by the 1st one. The result I want to obtain is a 4 by 2 matrix like this c'= [2205 300; 3535 600; 5944 600; 7281 300].
I also wrote a script to do it. For convenience, is there a buit-in function MATLAB to do it?
