this is my code .Please tell me what am I doing wrong
x0=[1;1;1];
xSol=fsolve(@(x) lor(x),x0)
function fval= lor(X)
conc= X(1);
temperature=X(2);
TA1=X(3);
Tss = 30 + 273.15;
C2 = 0.1068;
C3 = 17.55;
Gmin = 4;
Gmax = 20;
C1 = 62.5;
Tin = 10 + 273.15;
A = 3.18;
Cpcoolant = 1.0;
V = 16.2;
k0 = 5.04*10^10;
E = 9310;
F0 = 0.5;
C0 = 11.5;
H = 22.6*1000;
rho = 1108.1;
Cp = 0.865;
T0 = 26.8 + 273.15;
G = C3;
Cprime = 100*(G-Gmin)/(Gmax-Gmin);
if Cprime < 20
Qc = 22;
elseif Cprime > 85.56
Qc = .01;
else
Qc = -0.00511*(Cprime-20)^2 + 22;
end
U = C1*Qc^(1./3.);
fval(3,1) = temperature - (temperature-Tin)/(1+U*A/(2*Qc*Cpcoolant*60*453.59))-TA1;
fval(1,1)= (-V*k0*exp(-E/temperature)*conc - F0*(conc-C0))/V;
fval(2,1) = (H*V*k0*exp(-E/temperature)*conc...
- U*A*(temperature-TA1)/60 - rho*F0*Cp*(temperature-T0))/(rho*V*Cp);
end

Try to supply both x0 and fval as row vectors.
Best wishes
