[Numpy-discussion] Float view of complex array

[Jens Jørgen Mortensen]

Hi!

I have a view of a 2-d complex array that I would like to view as a 2-d 
float array.  This works OK:

 >>> np.ones((2, 4), complex).view(float)
array([[ 1.,  0.,  1.,  0.,  1.,  0.,  1.,  0.],
        [ 1.,  0.,  1.,  0.,  1.,  0.,  1.,  0.]])

but this doesn't:

 >>> np.ones((2, 4), complex)[:, :2].view(float)
Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
ValueError: new type not compatible with array.
 >>> np.__version__
'1.9.0'

and I don't understand why.  When looking at the memory layout, I think 
it should be possible.
