Hi, is there a guarantee that ufuncs will execute left to right and in sequential order ? For instance is the following code standards compliant ?
>>> import numpy as n >>> a=n.arange(0,5) array([0, 1, 2, 3, 4]) >>> n.add(a[0:-1], a[1:], a[0:-1]) array([1, 3, 5, 7]) The idea was to reuse and hence save space. The place where I write to is not accessed again. I am quite surprised that the following works correctly. >>>n.add.accumulate(a,out=a) I guess it uses a buffer and rebinds `a` to that buffer at the end. It is also faster than >>> n.add(a[0:-1], a[1:], a[1:]) --sean
