Hello there,
I'm having a few troubles in my matlab program. the problem his: Having a matrix like this: [2 2 0 4; 5 4 2 5; 8 6 1 4; 1 2 4 2; 56 50 30 49] i would like to be able to sort it ascending by the last line (56 , 50, 30 49). It would generate an output similar to this: [0 4 2 2; 2 5 4 5 ; 1 4 6 8 ; 4 2 2 1; 30 49 50 56]
All columns must move with the last one. Thanks in advance,
Andre

Get the indices for sorting the last row:
[~, I] = sort( data(end,:) );
And then reindex your matrix:
sdata = data(:, I);
