MATLAB: Can I name part of a variable after a string

horrible bad ideaMATLABnamerenamestringvariablevariables

Hello! I'm a new user, so sorry if I'm doing a stupid question, but here is my problem: Instead of having this program:
 CO2_Tc = 304.12;
 H2O_Tc = 647.14;
 Name = input('Input name: ','s');
 switch Name
    case 'CO2'
        T = input('Input temperature: ');
        Tc = CO2_Tc;
        Tr = T/Tc
    case 'H2O'
        T = input('Input temperature: ');
        Tc = H2O_Tc;
        Tr = T/Tc
    otherwise
        disp('Invalid name')
end
Could I have something like:
 CO2_Tc = 304.12;
 H2O_Tc = 647.14;
 Name = input('Input name: ','s');
 T = input('Input temperature: ');
 Tc = (Name)_Tc; %Here, Name would be replaced by the user's input, like CO2 or H2O
 Tr = T/Tc
Is it possible?

It is possible, but firmly not recommended

What I would recommend in your case is to have something like
Tc_vals = struct('CO2', CO2_Tc, 'H2O', H2O_Tc);
and then you could use
Tc = Tc_vals.(Name);
