Curve fitting ...

Hello there,
I have a problem on curve fitting , would you please help me ?!
I want to to develop a application that reads a text file with 2 columns of floating point data (as x and y) and performs a polynomial curve fit of the data at the order specified by the end user and then provides the curve-fit coefficients
as well as the curve fit errors.
My problem is in curve fit errors , I want to abtain Max and L2-norm of error.
In addition I use "matplotlib.mlab module " and polyfit function for computing polynomial curve fit.
Regards.

I would recommend using “pylab.load”
for reading the data. For example:

x, y = pylab.load(“filename”,
unpack=True) # with other options as required
