[Numpy-discussion] Memory leak in vectorize ?

2007-10-07 Thread Cyrille Rosset
Hello, the following code seems to create a memory leak in Python. (around 230 MB). Any ideas what's wrong ? I'm using python 2.5 and numpy 1.0.3 --- def toto(x): return x**2 tutu=vectorize(toto) Nbins=1 for i in xrange(1000): c=tutu(arange(Nbins)) --

[Numpy-discussion] Interested in adding new data type

2007-10-07 Thread Neal Becker
I'm interested in experimenting with adding complex data type. I have "Guide to Numpy". I'm looking at section 15.3. It looks like the first thing is a PyArray_Desc. There doesn't seem to be much info on what needs to go in this. Does anyone have any examples I could look at?

Suppose I have a function F(), which is defined for 1-dim arguments. If the user passes an n>1 dim array, I want to apply F to each 1-dim view. For example, for a 2-d array, apply F to each row and return a 2-d result. For a 3-d array, select each 2-d subarray and see above. Return 3-d result.
