sort a 2x4 matrix

I have 2x4 matrix and would like to sort the first row from smallest number to largest number, but I would also like the second row to follow along.

V=[9 3 5 2; 30 49 22 354]

Iwant=[2 3 5 9; 354 49 22 30]

Answer 1

[~, sortIdx] = sort(V(1,:)); 
Iwant = V(:,sortIdx);

Thank you! Just what I needed.

Glad I could help!

Star Strider also had a good idea to use sortrows(). I did a speed test between these two solutions and found that the one I proposed is ~2.7 times faster on average (100,000 repetitions of each; p<0.0001 wilcox rank sum test).

you could try doing:

V=[9 3 5 2; 30 49 22 354];
V_orderd=[];
 V_ordered(1,:)=sort (V(1,:));
V_ordered(2,:)=sort(V(2,:),'descend');
