I am fitting a set of data using nlinfit as magnetic dipoles and I want my fitted parameters to be only positive.

How do I make this constraint?

Put them in the fittype equation as parameters-squared.

Yes, put the parameters squared in the fittype function and square the results after solving.

Best wishes
