Sort a matrix based on one row?
显示 更早的评论
lets say we have a 3x3 matrix as
a= 2 5 3;
2 8 1;
4 1 9;
and I want this matrix sorted based on its 2nd row in ascending order i.e.
answer= 3 2 5;
1 2 8;
9 4 1;
Thank you for any help you can offer.

[temp, order] = sort(a(2,:));
answer = a(:,order);

Another solution:
answer = sortrows(a', 2)';

answer = sortrows(a.', 2).';
Using transpose, rather than complex conjugate transpose.
