[SciPy-User] polyval, polyfit on 2D array

[markus.proeller at ifm.com]

Hello everyone,

I have a two dimensional array with a shape of (600,800) and want to apply 
polyval and polyfit on each of the 600 lines.
Is there an elegant way to avoid a for loop over axis 0?
So for one line my code would be this:

>>> x=arange(800)
>>> p = polyfit(x, y[0,:])
>>> y_new = polyval(p, x)

Thanks for help,

Markus
