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.
