I apologize for not following up on this thread right away. I was sick for a couple of days and then there were several major severe weather outbreaks that required me to spend more time at work. With this said, I've resumed trying to build a DMG with Python2.5. The "export" suggestion below wor

[Numpy-discussion] embedding/extending numpy:import _array() problem

Hi guys, I've a C++ code that calls a python script. The python script, in turn, should use C modules to retrieve data (arrays). I'm having some problem with import_array. I've placed the import_array() just after the initialization of the interpreter and after PyInit_module Py_Initialize

[Numpy-discussion] BUG: NumPy exposes the wrong include directory

Hi all, Under Ubuntu, the NumPy headers are dumped under /usr/include/python2.6. This is not the location that should be exposed when another copy of NumPy is installed. The attached patch lets from numpy.distutils.system_info import get_info print get_info['numpy'] return the correct path. H

[Numpy-discussion] 3d plane to point cloud fitting using SVD

Dear Numpy Users, I want to fit a 3d plane into a 3d point cloud and I saw that one could use svd for this purpose. So as I am very fond of numpy I saw that svd was implementented in the linalg module. Currently I have a numpy array called xyz with n lines (number of points) and 3 columns (x,y,z

Just to make this thread more useful for someone interested in these topics, this seems to be "the book" on automatic differentiation (it's one of the references in the autodiff website) "Evaluating Derivatives: Principles and Techniques of Algorithmic Differentiation" (2nd ed.), by Andreas Griewa
