[Numpy-discussion] Boolean output for Object arrays with M

Hi Chuck, O.K. I've finally caught up with you, I think (at least as far as the umath generators go). All TD(M,.) lines should *not* have out='?' The reasoning is that this specifies a ufunc type with object inputs and boolean array outputs where the function is a method of the object

[Numpy-discussion] Code generator bug and fix?

I've gotten my own python class with a logical_not method to work correctly if I goto numpy/core/code_generators/generate_umath.py and change 'logical_not' : Ufunc(1, 1, None, 'returns not x elementwise.', TD(noobj, out='?'), TD(M, f='logical_not', out='?'),

I succeeded in working around the other Yellow Dog Linux porting problem connected with the floating point exception calls. It turns out that a problematic #include was protected by a "#ifdef __OPTIMIZE__" so my preprocessing with "gcc -E" never saw its effect. So, by avoiding optimization of u

In the following example I can sum up lists of column indices: >>> x = numpy.arange(30) >>> x.shape = (6, 5) >>> x array([[ 0, 1, 2, 3, 4], [ 5, 6, 7, 8, 9], [10, 11, 12, 13, 14], [15, 16, 17, 18, 19], [20, 21, 22, 23, 24], [25, 26, 27, 28, 29]])

Hi, I am pleased to announce the 0.6.1 release of numscons. You can get tarballs, eggs for python 2.4/2.5 and windows installers on launchpad: https://launchpad.net/numpy.scons.support/0.6/0.6.1 I did not announce any release of numscons for some time, but this one is a significant milesto
