Hey,

I'm using lsqnonlin to solve a problem. I have to use it without bounds because it uses the Levenberg-Marquardt algorithm that does not handle bound constraints.

However, I would like to remove the displayed informations using :

options = optimset('Display','off') ;

I tried :

p = lsqnonlin(F,p0,'options')

but it returns an error, expecting bounds as third argument. I need to mention that I could put some arbitrary bounds in third argument, but it also returns me an error as the Levenberg-Marquardt algorithm that does not handle bound constraints.

How do I do that ?

Thanks a lot
