How to dynamically create symbolic variables?

Hello,
I'm looking for a way to dynamically create symbolic variables.
For example with the code,
clear all
index = '1';
List = ['A','B','C'];
for i = 1:numel(List)
Temp = [List(i) index]
end
Is there a way I can create symbolic variables with the string stored in Temp?
Thank you, Kevin

Edit
index = {'1'};
List = {'A','B','C'};
Temp=strcat(List,index)
A=sym(Temp)

A=sym('A', [1 10]) creates a vector of syms 'A1','A2','A3',...
Is there a way I can create 'A1','B1','C1' using a similar syntax?

Is there a way to ensure that the symbolic variables are real?

Hello, can I create a matrx in the same way? e.g.
D = [D_11 D12
D_21 D_22]

D = sym('D_%d%d',[2,2]);
D(1,2) = sym('D12') ;
I do not know why the one entry is not to follow the pattern, but here it is.

for i=1:2 for j=1:2 D(i,j)=sym(['D_' num2str(i) num2str(j)]) end end
