curve start and finish at [0 0] [0 365] respectively?

how can i impose the fitting curve to start from [0 0 ] and finish in [0 365] ? possibly using curve fitting toolbox?

There are multiple ways to do this:

Trim your data before ... e.g.

x_new = x(x>=0 && x<=365);

same for Y of course

Trim your data in the curve fitting app.

e.g. under tools - exclude outliers

or in the fit options you can specify a range

Fit manually

and use tools like https://de.mathworks.com/help/curvefit/excludedata.html

Let (x,y) be your data.

idx = y >= 0 & y <= 360 ;

x = x(idx) ; y = y(idx) ;
