Function works with one input but not the other

Im using the optimisation tool and have set everything up following the tutorial on the mathwork website, the tool works when the input is Y but not when the input is T_to, which is what id like it to be. T_to input only works when the number of variables is one, which doesnt give me a useful result.
I should disclose im still very new to matlab so its possible that the problem is very simple.
function F = mymulti1(T_to)
y = 20640000;
%T_to = 3050; %degC
A_choke = 0.0531; %m^2
A_Rat = 78;
A_Exit = A_choke * A_Rat; %m^2
T_Exit = 343.2;
M_Exit = 1.65; %Ratio
Gamma = 1.26; %Const
Gas_const = 287.5; %Const
MFR = ((A_choke * y) ./ (sqrt(T_to))) * (sqrt(Gamma / Gas_const)) * ( ((Gamma + 1) / 2)^-((Gamma + 1) / 2*(Gamma - 1)));
Pressure_Exit = (1 + ((Gamma - 1) / 2) * ((M_Exit) ^ 2))^ - (Gamma /(Gamma - 1)) * y;
Velocity_Exit = M_Exit * sqrt(Gamma * Gas_const * T_Exit);
Thrust = (MFR .* Velocity_Exit) + (A_Exit * Pressure_Exit);
F(2) = Thrust ./ MFR ;
F(1) = (y .* A_choke) ./ MFR;
end

F(2,:) = Thrust ./ MFR ;
F(1,:) = (y .* A_choke) ./ MFR;
Check the size of output matrix
