Dag, Thanks for the link to your CEP. This is the first time I've seen it. You probably referenced it before, but I hadn't seen it. That CEP seems along the lines of what I was thinking of.We can make scipy follow that CEP and NumPy as well in places that it needs function pointers.

Re: [Numpy-discussion] change masked array member values with conditional selection

Ciao Chao, That known quirk deserves to be better documented, I agree. There's a simple explanation for this behavior: Because `a` is a masked array, `(a < 5)` is also a masked array with dtype=np.bool, and whose mask is the same as `a`'s. In your example, that's: masked_array(data = [-- -- -- Tr

Re: [Numpy-discussion] mask array and add to list

Use 'ma.max' instead of 'np.max'. This might be a bug OR an undocumented feature. :-) import numpy.ma as ma marr = ma.array(range(10), mask=[0,0,0,0,0,1,1,1,1,1]) np.max(marr) 4 # mask is used a = [] a.append(marr) a.append(marr) np.max(a)

[Numpy-discussion] change masked array member values with conditional selection

Dear all numpy users, I am using numpy 1.6.1 I find that if you want to change some member values in a masked array according to some conditional selection. suppose a is a masked array, you want to change all value below zero to zero. you must always use a[np.nonzero(a<0)]=0 rather than a[a<0]=

[Numpy-discussion] Segmentation fault during tests with Python 2.7.2 on Debian 6?

Hi, I'm trying out various continuous integration options, so I happen to be testing NumPy on several platforms that I don't normally use. Recently, I've been getting a segmentation fault on Debian 6 (with Python 2.7.2): Linux debian6-amd64 2.6.32-5-amd64 #1 SMP Thu Mar 22 17:26:33 UTC 2012 x
