How to turn off function values when using fsolve. ('Display','off') is not doing anything that is need it to do.

My code is

 options = optimoptions('fsolve','Display','off')
x0=[0.9;0.5;0.5];
xss=fsolve(@growthrate,x0,options)
%xss is the non-trivial steady state
x1=[1;11;1];
w=fsolve(@growthrate,x1,options)
W=round(w)
%w is the washout steady state

The output for the code is

How can i get the code to only display the values for xss, w, and W respectively. I do not want the "f=" values for each iteration to show up in my code. I tried playing around with the options and omtiset commands.

We need to see the code for growthrate

Answer 1

[Alan Weiss]

As Walter suspects, I believe that in your growthrate code you left off a final semicolon from the line of code that creates f. I mean, in that code, you have a line like

f = a + b - c

when you should have

f = a + b - c;

(I am just making up a line of code that calculates f; the point is, it should have a semicolon at the end.)

Yes, exactly what I was thinking.
