Hello everybody. I'm using a DEE box in simulink to implement 5 differential equations, but there is a syntax error in what I wrote. Can you find it?

The expression: ((C2*(Ta-u(19))+C3*((C5.^4)-(u(19).^4))+C3*((Ta.^4)-(u(19).^4))+C4*(u(20)-u(19))+c(1))/C1) in 'provaDEE/DEE/x1' has a syntax error

Answer 1

I am also getting same errors by using simulink dee block in matlab2019a. The equations are

(u(2)*(C_sc-x(1))/W)-k*x(2)*x(1)

(Ra*(O_in-x(2))/Wa)-(((n+2+((n+4)*sig))*k*x(2)*x(1)*W)/(4*M_c*Wa*(1+sig)))

(T_ri1*u(2)/W)+(T_a*u(1)*c_pa/(W*c_ps))-(x(3)*(u(2)*c_ps+*c_pa)/(W*c_ps))-(delH*k*x(2)*x(1)/(c_ps*M_c))

Can you attach the file with your code? Not paste it in, attach it - in case there is something that would not show up when pasted
