I keep getting an error during the running process, I don’t know which part is apart from the problem, please help.

Hi,

it even tells you the error, you are dividing by zero. The problematic equation is in line 35 where you have kappa/((1-tao_no)*(1+R_K)*(K_P(2)-K_P(1))).
This boils down to kappa/0, which is not possible.

Thanks for your reply. I have fixed it ,then it work. But a new problem comes out, please help me check this out.
it shows:

It seems you are trying a linearized model, but there are some equations that are nonlinear.
