Hi everyone, i am trying to simulate the following function but I keep on getting the error message
Error uing + Arrays have incompatible sizes for this operation. I would be very grateful if anyone can help me solve the error. Thanks
function F = CSTR_T(x)
global F_i C_Ai T_i T_c C_A T
C_A = x(:,1);
T = x(:,2);
V = 7.929;
rho_A = 823.2;
rho_B = 1008;
C_pA = 120.7;
C_pB = 75.46;
A_o = 17000000000000;
delta_H = -90000;
UA = 360000;
E = 7236;
R = 8.314;
a(i)= F_i(i)./V;
gamma = rho_A*C_pA + rho_B*C_pB;
z = UA/(V*gamma);
b = delta_H/gamma;
F(1) = C_A - ((F_i(i)./V).*C_Ai(j)/(F_i(i)./V + A_o*exp(-E/(R*T))));
F(2) = T - ((F_i(i)./V.*T_i(k) + b*exp(-E/R*T)*C_A + (z+T_c))/(F_i(i)./V + z));
end
