MATLAB: How to ensure that dynamically create symbolically variables are real

realsyms

Hello,
I'm creating symbolic variables dynamically and I wanted to ensure that the symbolic variables are real.
I have the code
clear all
index = {'1'};
List = {'A','B','C'};
A=sym(strcat(List,index))
How can I modify this to make sure that the symbolic variables stored in A are real? I have tried changing to A=sym(strcat(List,index),'real'), but this doesn't work.
I'm looking to do something like
    syms A1 B1 C1 real
    A = [A1 B1 C1]
except I want to declare the variable names dynamically.
(I can't assume that List will contain alphabetically ordered letters. It is whatever list the user inputs.)
Thank you, Kevin

clear all

A=sym(sym(strcat(List,index)),'real')
