How to write a function of two variables, but only use one?

So I have got the following problem: I have a function that depends of two variables f(T,X2L) but I have to give values to X2L from 0 to 100 using X2L = [0:0.1:100] so I end up with 1000 ecuations to solve for every value of X2L. The problem is, when I create the function f(T,X2L) I dont know how to tell matlab "okay we are going from 2 variables to 1 and I want you to create 1000 ecuations". Also, once I got all the equations, which is the easiest way to solve them all? Thanks in advanced!

In case you need the funtion or didnt understand what I mean heres what I tried out:

%Constants of the function (these are just constants, believe me)
HVAP1 = 41400; HVAP2 = 38800;
TVAP1 = 99.974+273.15; TVAP2 = 78.32+273.15;
TACEO001 = 78.18+273.15; X2ACEO0005 = 0.893;
B =(HVAP2*X2ACEO0005^2*(1/TVAP2-1/TACEO001)-HVAP1*(1-X2ACEO0005)^2*(1/TVAP1-1/TACEO001))/(HVAP1*(1-X2ACEO0005)^2*(1-4*X2ACEO0005)*(1/TVAP1-1/TACEO001)-HVAP2*X2ACEO0005^2*(3-4*X2ACEO0005)*(1/TVAP2-1/TACEO001));
OMEGA = HVAP1*(1-TACEO001/TVAP1)/((1+3*B-4*B*X2ACEO0005)*X2ACEO0005^2);
R = 8.314472;

%My problem
X2L = 0:0.01:100;
Funcion =@(T,X2L) exp(OMEGA./(R.*T).*(1+3*B-4*B.*X2L).*X2L.^2+HVAP1/R.*(1/TVAP1-1./T)).*(1-X2L)+exp(OMEGA./(R.*T)*(1+B-4*b*X2L).*(1-X2L).^2+HVAP2/R.*(1/TVAP2-1./T)).*X2L-1;
%I have to solve T(X2L) for every ecuation in the linspace X2L = 0:0.01:100
%so now i should do...???
Funcion(T,X2L) %this wont work as i didnt give any value to "T"

The only way I can think of :

syms X2L T
Funcion =exp(OMEGA./(R.*T).*(1+3*B-4*B.*X2L).*X2L.^2+HVAP1/R.*(1/TVAP1-1./T)).*(1-X2L)+exp(OMEGA./(R.*T)*(1+B-4*B*X2L).*(1-X2L).^2+HVAP2/R.*(1/TVAP2-1./T)).*X2L-1;
X2L = 0:0.01:100;
eqns=subs(Funcion,X2L);
TL=zeros(1,numel(eqns));
for i=1:numel(eqns)
TL=solve(eqns(i),T);
end

Okay, Thanks you very much for being this quick! now with this I think I have the ecuations that I need to solve, but how can I solve them?

I now tried the following:

TFuncion = subs(Funcion,X2L);
TFuncion == 0;
TL = solve(TFuncion,T)
%but matlab sends the error "Undefined function or variable 'T'." Although we defined it before.

Also, I didnt forgot to give a value to "b", it was supposed to be B, sorry!
