MATLAB: Error using optimset(@lsqnonlin) matlab 2020b

2020blsqnonlinoptimset

Hi,

I'm having trouble using optimset () for lsqnonlin () function. I am using matlab version 2020b.

…

options = optimset(@lsqnonlin)
X = lsqnonlin('filtroRC', X0, [], [], options, Vin, t, Vout_e)

…

Error using optimset (line 163)

No default options available for the function 'lsqnonlin'.

I would appreciate suggestions

Hi,

Yes, you can use optimset. You can directly use fmincon istead of createOptimProblem(but both work the same).

Hope this helps!

Try this:

options=optimset('fmincon');
options.Display='iter';
options.Algorithm='sqp';
