MATLAB: Sort every single row

sort

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

Try this:

    M = magic(4);
    N = 10;
    [ b, ix ] = sort( M(:), 'descend' );
    [ rr, cc ] = ind2sub( size(M), ix(1:N) );
    for ii = 1 : N
       disp( M( rr(ii), cc(ii) ) )
    end

x = [1 2 3 4; 5 6 7 8; 9 10 11 12; 13 14 15 16] 
y = [16 15 14 13; 13 14 15 16; 17 18 19 20; 21 22 22 23]
v = zeros(k,l);
for k = 1:numel(x)
    for l = 1:numel(y)
        v(k,l)= d(x(k),y(l));
    end
end

Note: The same can be achieved using meshgrid() or ndgrid(). I haven’t see the function d() if it’s properly vectorised you can take advantage of implicit expansion.
