Fail to parametrize InitDampling with optimoptions

Hello,

I'm trying to change InitDamping with optimoptions for lsqcurvefit and levenberg-Marquardt method.

opt = optimoptions(@lsqcurvefit,'Algorithm','levenberg-marquardt','InitDamping',1e2);

but InitDampling doesn't appear in properties and there is no impact on optim results.

Is this setting still tunable on actual version (R2020b and newer) ?

Kind regards,

Maxime
