How can I sort every single row of a matrix in ascending order? For example [16 2 3 13; 5 11 10 8] becomes [2 3 13 16;5 8 10 11] Thanks for help!

One way

    M = [16 2 3 13; 5 11 10 8] ;
    for rr = 1 : size( M, 1 )
       M( rr, : ) = sort( M( rr , : ), 'ascend' ); 
    end

Doing this in a loop is poor MATLAB code. Use sort's optional second dimension argument instead:

>> A =   [16 2 3 13; 5 11 10 8]
>> sort(A,2)
ans =
   2     3    13    16
   5     8    10    11

This is faster, neater and much more robust.
