Simple question about curve fitting

7 views (last 30 days)
Hi everyone! I have a question about fitting a curve: I have two vectors x and y of same length and the curve y(x). I want to fit this curve with a gaussian and I use the command
How can I fit my curve with this function but only between two points (x1,y1) and (x2,y2), where x1,x2 are two elements of vector x and y1,y2 the corresponding values of vector y? thank you in advance

aurc89 - find the indices of x1 and x2 within your x vector and then fit the curve against x and y using these indices. For example, if idx1 and idx2 are the indices of x1 and x2 such that x(idx1)==x1 and x(idx2)==x2 then fit the curve between these two points as
