[SciPy-User] Points fitting (non lin)

[Paolo Zaffino]

Dear Paweł,
thank you for the reply.
I try to explain better the issue.
I have these points (in this order):

P1 = (1,1)
P2 = (2,2)
P3 = (4,2)

P4 = (3,1)

I need to fit the points in the order P1,P2,P3,P4 even if the x coord of P3 is greater than P4.
I thought to quadratic piecewise curve but other solutions are welcome.

Thanks a lot.
Paolo

Dear Paolo,

I'm not sure I understand correctly your problem, but this sounds like a spline fitting job. You can read more about this here: http://docs.scipy.org/doc/scipy/reference/tutorial/interpolate.html 

Is this what you are looking for?

Cheers,



Paweł
