A = [8 4; 3 6; 2 7; 1 4; 2 3;2 1;3 1; 3 5; 8 6; 8 1];
B = sortrows(A);
I want to get the following output
ans = 2 1;
2 3;
1 4;
3 5;
3 6;
2 7
I want to get only the minimum row for every column.
I have 2 1 and 3 1 in the above array. Here minimum row for column 1 is 2. so i want only 2 1 .
Similarly i have elements 1 4 and 8 4 in the above array. Here minimum row for column 4 is 1. So i want only 1 4.
Please let me know how this is done in MATLAB
Looking forward to hear from you
Thanks
