[Numpy-discussion] numpy.fromfunction() doesn't work as expected?

Hi All,
I have spot a strange behavior of numpy.fromfunction(). The sample codes are
as follows:
>>> import numpy as np
>>> def myOnes(i,j):
return 1.0
>>> a = np.fromfunction(myOnes,(2000,2000))
>>> a
1.0
Actually what I expected is that the function will return a 2000*2000 2d
array with unit value. The returned single float value really confused me.
Is this a known bug? The numpy version I used is 1.6.1.
Regards,
Cheng
