Andrew,
I have used your setup script.
However, I get into trouble
from scipy import *
import matfile
load("matrizen_red.mat")
#io.loadmat("matrizen_red.mat",appendmat=0)
Traceback (most recent call last):
File "matlab.py", line 3, in ?
load("matrizen_red.mat")
File "/usr/local/lib/python2.1/site-packages/Numeric/Numeric.py", line
506, in load
return Unpickler(file).load()
File "/usr/local/lib/python2.1/pickle.py", line 554, in __init__
self.readline = file.readline
AttributeError: readline
Any suggestion ?
