[Matplotlib-users] Problems with quiver?

[Chris N. <ca...@gm...>]

I am trying out quiver using IPython (which I am new to so my apologies if=
=20
this is actually a IPython question) and matplotlib .80 and the latest=20
numeric. The code I try and the subsequent error:

In [1]: x=3Dones([5,5])

In [2]: quiver(x,x)
---------------------------------------------------------------------------
exceptions.TypeError Traceback (most recent call last)

C:\Documents and Settings\root\Desktop\<console>

C:\Python24\Lib\site-packages\matplotlib\pylab.py in quiver(*args, **kwargs=
)
2137 hold(h)
2138 try:
-> 2139 ret =3D gca().quiver(*args, **kwargs)
2140 draw_if_interactive()
2141 except:

C:\Python24\Lib\site-packages\matplotlib\axes.py in quiver(self, U, V,=20
*args, **kwargs)
852 if do_scale:
853 Nmax =3D maximum.reduce(maximum.reduce(N))
--> 854 U *=3D (S/Nmax)
855 V *=3D (S/Nmax)
856 N /=3D Nmax

TypeError: return array has incorrect type


What could be the issue? Thanks for the help.
