Fitting only one parameter of a function with many parameters in python

Question

In python I have a function which has many parameters. I want to fit this function to a data set, but using only one parameter, the rest of the parameters I want to supply o

Answer 1

There is a simpler option if you are willing/able to edit the original function.

Redefine your function as:

def func(x,a):
    return a*x*x + b

Then you can simply put it in your loop for parameter b:

for b in xrange(10):
   popt,pcov = curve_fit(func, x1, x2)

Caveat: the function needs to be defined in the same script in which it is called for this to work.
