WebDec 2, 2024 · Instead, use fsolve (from the optimization toolbox) or solve/vpasolve (from the symbolic toolbox), or lacking those TBs, you could even use fminsearch. And if you cannot figure out how to implement it with fminsearch, then it is trivially simple to just solve the second equation for t, then substitute into the first equation. WebAug 22, 2016 · Matlab limitation in fsolve using function input. I tried to loop for time value (T) inside my fsolve, but fsolve is pretty unforgiving. The time loop does not seem working. When I plot, it gives the same values (h=x (1) and theta=x (2) does not change over time which should change)! Please see the the script that uses for loop for time (T).
