[Numpy-discussion] removing references to Scipy Core

2007-05-21 Thread Jarrod Millman
Hello, I noticed that there are a few places where Scipy Core is still referenced: 1). On http://numpy.scipy.org/new_features.html the title is still Scipy Core even though the heading has been updated: " New Features of SciPy Core New Features of NumPy" 2). If you do a search for "scipy"

I would have to say that I agree with Robert. We (STScI) are about to force all of our users to install numpy. For some of them that can be a lot to ask. I don't also want to add the extra complication of upgrading their Python version as well. My feeling is that not everyone has made the ju

Hi, I noticed that numpy revision 3794 introduces `set` but that is available starting from Python 2.4. Hence the question. Best regards, Pearu ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy

2007-05-21 Thread Robert Cimrman
I have come to a case where using a matrix would be easier than an array. The code uses lots of dot products, so I tested scipy.dot() performance with the code below and found that the array version is much faster (about 3 times for the given shape). What is the reason for this? Or is something wro
