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;

Where is the line causing this error?

Walter Roberson 2013-10-12

在 MATLAB Online 中打开

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.

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

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.
