Working with different variables in Cycle

Hi i have question.

Basically i have a for cycle and in every iteration I would like to use different Variable.

I have for example Variable C which is matrix and I want to use first column and all rows so C(:,1). I have several variables with different names like D1, D2, T1, T2 and so on.

So in the first iteration i=1 I want to use variable C and in i=2 variable D2 and so on.

Now I looking for a way how to manage it. I tried some cell2mat but it didn't work.

Part of the code I have:

Par = cell2mat(Param(i)) % In Param cell i have stored names of variables where Param(1)=C and Param(2)=D1 for example

ind = find(P_VB(1,1)==Par(:,1));  %Now i would like from matlab to substitute Par with C is it would be ...C(:,1);

Hope it makes sense what i want to achieve.

Thanks a lot.

Using D1, D2, ... als variables must lead to such problems, see: FAQ: Create A1, A2, ... in a loop. And if you have loaded the FAQ already, take the time to read the other topic also.

Better use the cell array D{1}, D{2}, ... Then the variables are easy to access inside a loop.

Yes this helped me to resolve my problem. Appreciate a lot Jan. And a brief question. I created a cell with A=cell(12,1) How can I add all my variables with one command to the array A? like A{}=[A B C D ...]

Now i have to write it one by one like: A{1}=A; A{2}=B; A{3}=C;

Thanks
