[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
