oh brother -- so now I've got to deal w/ Apple...

okay thanks.

here's where I am.

I've downloaded matplotlib, numpy, python 2.7.3, xcode and macports to

simply plot this oh-so-simple code!

Which is:

Curve fitting with python and pylab

#import the lib

from pylab import *

# assuming this data set

t = (0,5,10,15,20,25,30,35,40,50)

V = (1,7,14,15,16,22,25,27,28,30)

#show the data

plot(t, v, linewidth=2.0)

#assume an order

N = ?

#find the coefficient of the polynomial

coeffs = polyfit(t,v,N)

#get the polynomial output for the input

best = polyval(coeffs, t)

#print the coefficients

print(coeffs)

I have written it like this in python 2.6:

import os,sys

import numpy

#import pylab

t = (0,5,10,15,20,25,30,35,40,50)

V = (1,7,14,15,16,22,25,27,28,30)

#scipy.plot(t,v,linewidth=2.0)

n = 4

coeffs = numpy.polyfit(t,V,n)

best = numpy.polyval(coeffs,t)

print coeffs

print best

and when I run the program, I get this:

[ -1.68165168e-05 1.71262071e-03 -6.39152514e-02 1.59163337e+00

1.04578755e+00]

[ 1.04578755 7.60964036 12.11505162 15.46811522 18.32267732

21.08033633 23.89044289 26.6500999 29.0041625 29.81368631]

when I run in 2.7.3 it looks like this:

import os,sys

import numpy as np

import pylab

t = (0,5,10,15,20,25,30,35,40,50)

V = (1,7,14,15,16,22,25,27,28,30)

#scipy.plot(t,v,linewidth=2.0)

n = 4

coeffs = numpy.polyfit(t,V,n)

best = numpy.polyval(coeffs,t)

print coeffs

print best

And my error msg is this:

ImportError: No module named numpy

any ideas?

What I'm looking for is a visual.
