[SciPy-user] numpy install errors

[Alastair Basden]

Hi,
installation now okay - was something to do with environment variables, 
though not sure which ones...

So the question now is why does the following happen:

>>> import scipy.special
>>> scipy.special.kv(6./5,1)
0.70066931017889988
>>> scipy.special.kv(6./5,1)
0.70066931017889988
>>> scipy.special.kv(6./5,1)
0.70066931017889988
>>> scipy.special.kv(6./5,[1,1])
array([ 0.70066931,  0.70066931])
>>> scipy.special.kv(6./5,1)
6.1853203003937157e-282
>>> scipy.special.kv(6./5,1)
6.1853203003937157e-282

ie it seems to go wrong after the first ufunc is called... but is okay on 
single values...

Thanks...
