Problem with assigment loops variables with my loaded .dat

Hello I am trying to attempt the following. But the loop assingment is not working. The files load but are not assinging to flipud function. Any thoughts?

for z=10:10:100
   for i=1:10
   load(['2Dabs' num2str(z) '.dat'])
   load(['2Dabs2_' num2str(z) '.dat'])
   load(['2Dabs3_' num2str(z) '.dat'])
   load(['2Dabs4_' num2str(z) '.dat'])

     %A{i} = (['2Dabs' num2str(z) '.dat'])
     %A(i)=(['X2Dabs' num2str(z)])

     a(i)=flipud((['X2Dabs' num2str(z)]));

     end 
  end

Hi Orbicalaz,

What are you expecting to happen when you pass the string 'X2Dabs10' (or X2Dabs20/30/...) to the flipud function? Since the string is just a row of characters, nothing will change to that string. The documentation for this function (type help flipud at command line) reads as:

flipud Flip matrix in up/down direction.
    flipud(X) returns X with columns preserved and rows flipped
    in the up/down direction.  For example,

So there will be no change to the text since the columns are preserved and there is only the one row to flip.

@Orbicalaz: I've formatted the code to improve the readability.

What does "assinging to flipud function" even mean ???

What variables are in those mat files? And what do you expect the badly-named "a" or "A" to be if you got what you want? Are you expecting a scalar? A 2D numerical array? Or a 2D cell array? See this: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F
