Hi, I am new to this forum and have little experience with MATLAB. I would appreciate your help with the following question.
Is there a function or a toolbox in MATLAB that allows to estimate non-linear regression model parameters jointly?
I have two non-linear regression models to estimate jointly.
No products are associated with this question.
I do not understand what you mean by ‘jointly’, but there are three possible functions you can use: nlinfit (Statistics Toolbox), lsqcurvefit (Optimization Toolbox) or (with an extra line of code) the core MATLAB function fminsearch.
