I done my model in nonliear form
but when i try to run it ,but it has some error

I find someone say maybe the initval value is wrong
then i use the steady state value solve by hand to plug in
some i can’t solve i set by myself
but i t’s still wrong…
please tell me how to solve it … thank you for your help!
yoyo.mod (3.91 KB)
In your steady state computation, you have
omds= (2.0*v + 2.0*(mu*v - 2.0*v - 1.0*mu*v^2 + v^2 + 1.0)^(1/2) - 2.0)/(mu*v);
v=(1+omds*(1-bet^(2)*gam-0.5*mu)+omds^(2)*(0.5*bet^(2)*gam-0.5));
omds uses v, but v is only computed in the next line and cannot be used before.
Really really thanks to you !!jpfeifer
I solve the problem!^^!
but now I get some new problem

why there all NaN and INF QQ…?
matlab say divide by zere and log of zero
but I don’t know which equation is?
could you teach me how to solve it?
Thanks for your help!
