Hi,
I'm using the Debian package (version 0.2.1-1) of scipy.
While working my way through the tutorial trying out the examples,
I've stumbled on a few things. Can anyone help me out with these?
1. no attribute "standard_normal"
The code of Example 5.7 doesn't work:
>>> y_meas = y_true + 2*randn(len(x))
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "debian/scipy/usr/lib/python2.1/site-packages/scipy/basic1a.py", line 104, in randn
AttributeError: 'scipy.stats' module has no attribute 'standard_normal'
2. Example 6.3 calls grid incorrectly. This example shows
x,y = grid[-1:1:20L,-1:1:20L]
But the "20L" (presumably meant to be a length?) should really
be a stepsize. The above results in
>>> print x
zeros((0,), 'l')
I imagine what is intended is a stepsize of 0.1, i.e.
x,y = grid[-1:1:0.1,-1:1:0.1]
3. no xplt.plot3
The code of Example 6.4 has a line
xplt.plot3(x,y,z,shade=1,palette='rainbow')
But I can't find any plot3 functions at all.
I can see plot3d in a few places, but I haven't figured
out how to make Example 6.4 work with them.
Thanks,
-Steve
