it is a recent feature.
It works for me on version '0.9.9.2660'
pau
>>> import numpy
>>> numpy.__version__
'0.9.9.2660'
>>> a = numpy.rand(3,4)
>>> a
array([[ 0.24347161, 0.25636386, 0.64373189, 0.82730095],
[ 0.02062571, 0.12244009, 0.60053928, 0.10624435],
[ 0.75472591, 0.00614411, 0.75388955, 0.40481918]])
>>> I = a[:,0]<0.5
>>> J = a[0,:]<0.5
>>> a[numpy.ix_(I,J)]
array([[ 0.24347161, 0.25636386],
[ 0.02062571, 0.12244009]])
