Version 21.0a1 -- in CVS only
Please help me test the following. I have tested on Windows / Python
2.2.
Implement true division operations for Python 2.2 (Bruce Sherwood, our
hero).
New functions in Numeric; they work on any sequence a that can be
converted to a
Numeric array.
def rank (a):
"Get the rank of a (the number of dimensions, not a matrix
rank)"
def shape (a):
"Get the shape of a"
def size (a, axis=None):
"Get the number of elements in a, or along a certain axis."
def average (a, axis=0, weights=None, returned = 0):
"""average(a, axis=0, weights=None)
Computes average along indicated axis.
Inputs can be integer or floating types.
Return type is floating but depends on spacesaver flags.
If weights are given, result is
sum(a*weights)/sum(weights)
weights if given must have a's shape or be the 1-d with
length the size
of a in the given axis.
If returned, return a tuple: the result and the sum of
the weights
or count of values.
if axis is None, average over the entire array
raises ZeroDivisionError if appropriate when result is
scalar.
