Cell contents assignment to a non-cell array object.

Hey guys,

i do have this little code to program. what i dont understand is, when i run it without the inner for-loop, there is now error. when i run with the loop, there is this error that i dont understand. Anybody able to help me finding the bug ?

C = cell(28, 1);
for i=1:1:28;
  C{i} =  UM(i,:);
  IPV = C{i,1}(1);
  IB = C{i,1}(2);
  IWP = C{i,1}(3);
  IK = C{i,1}(4);
  IWS = C{i,1}(5);
  for p = 1:1:2;
   Bundesland=p;
  OptimierungPV_B_WP_mitWaermespeicher_Bandu_14;
   Kapitalwert(1,1) = num2cell(ZFW);
   if Bundesland == 1;
     xlswrite('testsheet.xlsx', ...
    Kapitalwert, ...
     'Kapitalwerte','A1:A28');
   elseif Bundesland == 2;
   xlswrite('testsheet.xlsx', ...
   Kapitalwert, ...
     'Kapitalwerte','B1:B28');
   end;
end;

end;

Is it possible that you had initialized Kapitalwert before this loop?

Where is the line causing this error?

[Walter Roberson]

The line with problems is likely

   Kapitalwert(1,1) = num2cell(ZFW);

which would be a problem if Kapitalwert exists but was not a cell array at the time of the assignment.

thanks for your help.

i solved the problem by renaming the cell array. I used the variable C already in the program i call in line 11 ("Optimierung ..."). that's why it worked for the first loop and stopped afterwards.

[Walter Roberson]

Ah. Usually we assume that calls to user routines are functions unless they are clearly scripts.

[Michael]

thanks for your quick answers.

@no, i have not initialized it yet. here, it is the first time i put it. why is it likely to be to be the problem and how may i solve it ?

@azzi: the line causing error is the third line.

thanks for your support.

The code you give is not going to have a problem at C{i} = UM(i,:) even if UM is a cell array. Not unless there is some additional code you have not shown, between the C = cell(28,1); and the code you show.
