Sachin,
BB,
I have picked python recently and use it for simple day to day task. I am
looking a routine for loading Well Log Las format and storing information as
arrays or List.
Las format looks like following
# LAS format
# Project units are specified as depth units

Came across an odd behavior with a numpy array of datetimes:
>>> import numpy as np
>>> from datetime import datetime
>>> a = np.empty((9, 20), dtype=datetime)
>>> a.fill(datetime.now())
This works:
>>> a.min()
datetime.datetime(2011, 3, 21, 15, 5, 10, 990733)
but, this fails:
>>> np.argmin(a)

Would using h5py or pytables help? I get about 3 ms for a write-read
cycle for a 200K array. That's much faster than the convo

Hey all, just wanted to let you know that this works nicely:
stacked = np.vstack(MyDict.values())
So long as the dictionary only cotains the recarrays.

hi, is there a way to take the product along a 1-d array in a moving
window? -- similar to convolve, with product in place of sum?
currently, i'm column_stacking the array with offsets of itself into
window_size columns and then taking the product at axis 1.
like::
w = np.column_stack(a[i:-windo

Hi Ben,
It's very easy to package numpy (and most other modules) with py2exe,
which like Dan mentioned above, will include all necessary (also non-python)
libraries into a dist-folder. The folder to distribute can of course get
quite large if you include a lot of libraries - but I think that onl
