Display numbered cell summary?

Hey everyone. I am doing some hw and am just about finished with my code. Our professor wants it to output this.

Part Direction Distance
__________________
1    N        5
2    E        4
3    N        4
4    W        2
5    N        1
6    S        2
~~~~~Final Location of Balloon~~~~~~
   N 8 E 2

This is what I have for the code that is supposed to output that.

fprintf('Part Direction Distance\n')
for k=1:n
   fprintf('%d %s\n',k,BalloonCellArray{k})
end
FinalDirection = '';
fprintf('~~~~~Final Location of Balloon~~~~~~\n');
if(VerticalLocation~=0)
    fprintf('   %s %g',VerticalDirection,VerticalLocation);
end
if(HorizontalLocation ~=0)
    fprintf(' %s %g\n',HorizontalDirection,HorizontalLocation);
end    
if(VerticalLocation==0)&&(HorizontalLocation==0)
    fprintf('   NO CHANGE\n');
end

But this is what it outputs instead.

    Part Direction Distance
      1 N
      2 E
      3 N
      4 W
      5 N
      6 S
      ~~~~~Final Location of Balloon~~~~~~
       N 8 E 2

I am trying to display a 6x2 cell called BalloonCellArray and I think I'm really close. Thanks for any help!

You're using linear indexing to index into a 2d cell array, so assuming that n is the number of rows, you're only indexing the first row. Use row, column indexing and index both columns in your loop. That is replace your fprintf with:

fprintf('%d %s %d\n', k, BalloonCellArray{k, 1}, BalloonCellArray{k, 2});

Note that using expansion of cell arrays into comma separated lists, the above can also be replaced with:

fprintf('%d %s %d\n', k, BalloonCellArray{k, :});

If you do use that second, you'd better put a comment explaining what's happening (by linking to the above doc for example).
