Sortrows_function of a Matrix

T=[1:10;40,43,18,43,34,18,23,31,44,38]';
T=ShortestTime(T)
T=LongestTime(T)
function [c]=ShortestTime(T)
c=sortrows(T,[2 1])
end
function [c]=LongestTime(T)
c=sortrows(T,[-2 1])
end

Hi, I wrote a little script to sort a matrix. But now I want that Matlab write only the first column of the matrix. How do I do that?

You can get the first column of a matrix by indexing like this

first_column = T(:,1);

Ok, thanks now it works. But when i run the script it write every time also the sortet Matrix.

But i want only that Matlab write the solution of the function: ShortestTime and LongestTime.

How can i do this?

T=[1:10;40,43,18,43,34,18,23,31,44,38]';
T=ShortestTime(T)
T=LongestTime(T)
function [c]=ShortestTime(T);
c=sortrows(T,[2 1])
ShortestTime = T(:,1)
end
function [c]=LongestTime(T)
c=sortrows(T,[-2 1])
LongestTime = T(:,1)
end

I am not sure about your question. Maybe you want to save them in different variables

T=[1:10;40,43,18,43,34,18,23,31,44,38]';
T1=ShortestTime(T);
T2=LongestTime(T);
