Hello,
I have an error in the function "lsqcurvefit" that I have to use, I tried to solve the problem but I don't know what the error is exactly, I have to know that I respect the syntax of the function.?
Thank you for your help

Neither the array "xdata" nor the array "ydata" appear in the definition of your function "fun". That's why you have only a single equation for the unknown vector x. I doubt this is what you want.

The error message mentions 'dot indexing', which means you have likely forgotten a multiplication symbol in your equation. I found this about halfway through your equation: Kth.x(2)
You probably meant to do elementwise multiplication: Kth.*x(2)

I linked to the corresponding page in the documentation.
You could also just attach your excel file using the paperclip icon, but you also need to then share the code that loads that spreadsheet as well as the code that creates the variables used when calling lsqcurvefit.
