[Numpy-discussion] A bug in repeat function?

[Nadav H. <na...@vi...>]

The repeat appears to accpt only short boolean array as repat counters:

>>> A
array([1, 2, 3])
>>> repeat(A, [1,1,1])
array([1, 2, 3])
>>> U =3D array([1,1,1], type=3DBool)
>>> U
array([1, 1, 1], type=3DBool)
>>> repeat(A,U)    # OK
array([1, 2, 3])
>>> A =3D arange(100000)
>>> U =3D ones(100000, type=3DBool)
>>> AA =3D repeat(A,U)   # U is too long --- an error is generated

Traceback (most recent call last):
  File "<pyshell#90>", line 1, in -toplevel-
    AA =3D repeat(A,U)

>>> AA =3D repeat(A,U)
