Fitting Custom Trendlines in MATLAB with fminsearch

Code: github.com/vas...
I show how we can use MATLAB to define unique functions for our trendlines and determine the best fitting parameters for those functions using fminsearch.

Thank you! I based my first Ph.D. project on this video. Already got a poster and oral presentation out of it and working on a manuscript.

Been trying to understand this all day. Thank you so much, you explained it really well. Now to find out how to use anonymous fn as well!

You just saved my project and my mental health :p Thanks!! :)

You’re welcome!

Would it be possible to show to do different functions with different sets of x, y data but same parameters? thanks

Thanks a million.

Hi Vincet, great video! I am also using fminsearch to fit a function and it works well. Now i need to assign an uncertainty to each parameter found by this method, but i do not know how to proceed, can you help me with that?
