Dear all,

I want to get a nonlinear fit curve, the equation is y=p1+p2*x^(-2)

how can I get it in origin?

Thank you for any help!

Hi Windy,

Origin allows you to define your own fitting function, and then you can use it as the origin built-in function. You can refer to the following link for more details:
