MATLAB: String problem

strings

I have the following code
Lev=7;
for i=1:Lev
 str=strcat('A',int2str(i));
  for j=1:3
      str(j,:)=squeeze(Atr(i,j,:));
  end
end
This program showing erros like
    ??? Subscripted assignment dimension mismatch.
Error in ==> attractor_test at 80
        str(j,:)=squeeze(Atr(i,j,:));
Actually, I want to assigne names in run time of the program execution. In the above code str have to take names like str —> A1, A2, A3, …A7 and store values in A1, A2, A3 ….A7 respectively..
How to do that in matlab ?

That is usually a bat thing to do. There is a busload of questions like this, and a good explanation in FAQ-s everywhere and the matlab newsgroup.
What I suggest you do instead is to use cell-arrays:
Lev = 7;
for i1 = 1:Lev
  str = strcat('A',int2str(i1));
  for j2 = 1:3
    A{i1}(j2,:) = squeeze(Atr(i1,j2,:));
  end
end
Also it is nice to avoid i and j as loop variables, sooner or later you'll get them jumbled with the imaginary i = (-1)^(1/2).
