Hi all,
The docstring for vander() seems to contradict what the function does. In
particular, the columns in the vander() output seem reversed wrt its
docstring. I feel like one of the two needs to be fixed, or is there
something I'm not seeing?
This here is fresh from the Numpy examples page:
8< docstring -----------------------------------------------
X = vander(x,N=None)
The Vandermonde matrix of vector x. The i-th column of X is the
the i-th power of x. N is the maximum power to compute; if N is
None it defaults to len(x).
8< Example -------------------------------------------------
>>> from numpy import *
>>> x = array([1,2,3,5])
>>> N=3
>>> vander(x,N) # Vandermonde matrix of the vector x
array([[ 1, 1, 1],
[ 4, 2, 1],
[ 9, 3, 1],
[25, 5, 1]])
8< ---------------------------------------------------------
