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.
