[Numpy-discussion] how to tally the values seen

I have an array that represents the number of times a value has been given. I'm trying to find a direct numpy way to add into these sums without requiring a Python loop. For example, say there are 10 possible values. I start with an array of zeros. >>> counts = numpy.zeros(10, numpy.int) Now

[Numpy-discussion] patch to pickle np.memmap

hi, i posted a patch to allow pickling of np.memmap objects. http://projects.scipy.org/numpy/ticket/1452 currently, it always returns 'r' for the mode. is that the best thing to do there? any other changes? -brent ___ NumPy-Discussion mailing list NumPy-

[Numpy-discussion] binomial coefficient, factorial

Is there any chance that a binomial coefficent and factorial function can make their way into NumPy? I know these exist in Scipy, but I don't want to have to install SciPy just to have something so "basic". ___ NumPy-Discussion mailing list NumPy-Discuss
