Re: [Numpy-discussion] f2py callback bug?

Hi, It is not really a bug what you are seeing.. In pycalc when assigning j = 20 * j you create a new object `j` and the argument object `j`, that links back to Fortran data, gets discarded. So, you can change j inplace, for example: j[:] = 20*j The first argument `i` is int object that in

[Numpy-discussion] Help making better use of numpy array functions

Hi I have written some code and I would appreciate any suggestions to make better use of the numpy arrays functions to make it a bit more efficient and less of a port from C. Any tricks are thoughts would be much appreciated. The code reads in a series of images, collects a running total if the v

Gokhan, Thank you for the referred repo. I'll keep this as a reference for future endeavours should I fail given my current approach. As for installing Python 2.6.4, that was very easily done as a parallel installation as I described. I'm more than happy to give you more details if you need the

Sorry I missed your message the first time around. I suspect you're running into this bug: http://projects.scipy.org/numpy/ticket/1235 This has been fixed in SVN r7514, (and thus 1.4 pre releases), so it's not a platform difference. The workaround (at the expense of performance, of course) is
