Re: [Numpy-discussion] Tuple outer product?

OK, sure, for large arrays meshgrid will look bad. (It creates a large array twice.) If the example really involves sequential integers, then mgrid could be used instead to save on this. Even so, it is just implausible that duplicating meshgrid functionality will be faster than using meshgrid. So

for numpy and scipy, only the tests have executable permissions. It's as if the tests were specifically targeted and had their permissions changed. And these are the only two python packages i've built from source and installed in this manner, other i've gotten via easy_install, or in the case of

Ah, I missed the fact that Numpy unicode characters are always 4-bytes, unlike Python unicode objects. Divide by 4 is easy enough. Sorry for the noise. Mike Michael Droettboom wrote: > Is there a way to get the number of characters in a fixed-size 'U' > array? I can, of course, parse dtype.

[Numpy-discussion] Getting number of *characters* in dtype='U' array

Is there a way to get the number of characters in a fixed-size 'U' array? I can, of course, parse dtype.str, or divide dtype.itemsize by the size of a unicode character, but neither seems terribly elegant or future proof. Does numpy provide (to Python) a method for getting this that I'm just

i have no clue why i'm having this problem. This is a fresh install of ubuntu as well as numpy and scipy... During the write to std out during build and install I do notice things like "changing permission for f2py from 640 to 755" or something like that. So i'm wondering if other permissions ar

Hi, I hope this is the right place to ask this. I've found the MFDataset works well in reading NetCDF3 files, but it appears that it doesn't work at present for NetCDF4 files. Is this an inherent problem with the NetCDF4 file structure, or would it be possible to implement the MFDataset for NetCDF

[Numpy-discussion] datetime functionality: questions and requests

Hi there, Hi Travis, I have started looking at the new datetime code, with the idea that we should soon fix (for real) a release date for numpy 1.4.0. I have a few requests and questions: - since npy_datetime is conditionally defined to be 64 bits, why not typedefing it to npy_int64 ?
