It is not a bug in numerix; numerix is using an older version of where, provided by numpy for compatibility with Numeric:
In [4]:numpy.where? Type: builtin_function_or_method Base Class: <type 'builtin_function_or_method'> String Form: <built-in function where> Namespace: Interactive Docstring: where(condition, | x, y) The result is shaped like condition and has elements of x and y where condition is respectively true or false. If x or y are not given, then it is equivalent to condition.nonzero(). To group the indices by element, rather than dimension, use transpose(where(condition, | x, y)) instead. This always results in a 2d array, with a row of indices for each element that satisfies the condition. In [5]:pylab.where? Type: function Base Class: <type 'function'> String Form: <function where at 0xb6e2a924> Namespace: Interactive File: /usr/lib/python2.4/site-packages/numpy/oldnumeric/functions.py Definition: pylab.where(condition, x, y) Docstring: <no docstring> Eric [EMAIL PROTECTED] wrote: > Hi, > > I think there are a bug in numerix.
