<p class="MsoNormal">Hello fellow Fieldtrip users,</p>

<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">So I was trying to compare different optimization methods for dipole fitting. I use Brainstorm, and found out that Brainstorm uses Fieldtrip’s function ft_dipolefitting for fitting dipoles, which eventually uses the fminunc or fminsearch

 for optimization purpose. </p>

<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal">So my question was that- <span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#222222;background:white">

Instead of using fminsearch or fminunc as specifies in the Fieldtrip ft_inverse_dipolefit, can we use other optimizers such as <code><span style="font-size:11.5pt;font-family:Consolas">fmincon</code><span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#222222;background:white"> , <code><span style="font-size:11.5pt;font-family:Consolas">fseminf</code><span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#222222;background:white"> , <code><span style="font-size:11.5pt;font-family:Consolas">lsqcurvefit</code><span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#222222;background:white"> , <code><span style="font-size:11.5pt;font-family:Consolas">lsqnonlin</code><span style="font-size:11.5pt;font-family:"Arial",sans-serif;color:#222222;background:white">?

 If yes, can we just change the optimfun to let’s say fmincon and run the optimization on fieldtrip, or only fminunc and fminsearch work for the purpose of dipole fiitings?

</span></p>
