[Numpy-discussion] f2py hiding callback function

2012-05-30 Thread Marc Poinot
Hi all, I'm trying to hide the actual python callback function on the fortran side as well as on the python side. See the example: I want f1 to be the wrapper of my callback, f2 is a second level where the user has no arg to pass. But if I call f2, for example in f3, the callback is 'propagated'

[Numpy-discussion] Numpy code in GPL package

I'd like to include the _cook_nd_args() function from fftpack in my GPL code. Is this possible? How should I modify my license file to satisfy the Numpy license requirements, but so it's clear which function it applies to? Thanks, Henry ___

[Numpy-discussion] fast access and normalizing of ndarray slices

Dear all, I have an ndarray which consists of many arrays stacked behind each other (only conceptually, in truth it's a normal 1d float64 array). I have a second array which tells me the start of the individual data sets in the 1d float64 array and another one which tells me the length.
