显示 更早的评论
Hello, i want to sort a line of the matrix and change the other lines according the line sorted. For example, i have a matrix like this:
a = [5 3 4 2 6; 1 2 3 4 5].
i want to sort line 1 and change line 2 according the sort of line 1, like this:
aSorted = [2 3 4 5 6; 4 2 3 5 1]
How can i do that??
Thank you for your help.

Use sortrows.
a = a'; % transpose your matrix
asorted = sortrows(a,1); % sort by first column (row)
asorted = asorted'; % de-transpose your matrix
You can combine all that code into one line:
asorted = sortrows(a')';

[~,ii] = sort(a(1,:));
out = a(:,ii);
