multicomponent fitting

[Dirk Dom]

Hello,

For several years we have been using Easyspin to do some spectral fitting on our ERP-spectra, mainly for multicomponent systems. So far so good.

But since the last update of Easyspin 6.0.4, running in a quite new version of MatLab (R2024a), our fitting procedure is not working anymore... We always get errors on too many variables etc which are apparently not so easy to solve. A.I. was also not so useful. Our plotting file still works as we want, so it's not a license issue...

Our MatLab code is in attachment.

Anybody with tips to resolve this?

Thanks

Dirk, the problem lies with how you call esfit. The interface for esfit has changed from ES 5 to ES 6. Please refer to the documentation on least-squares fitting. On the documentation site you can also find a migration guide from ES 5 to 6.
