indexing with arrays of indexes and +=

[Vincent Schut]

It is clear to me that the numpy += operator in combination with the use 
of arrays of indexes, as is explained in the Tentative Numpy Tutorial 
(http://www.scipy.org/Tentative_NumPy_Tutorial#head-3f4d28139e045a442f78c5218c379af64c2c8c9e), 
the limitation being that indexes that appear more than 1 time in the 
indexes-array will get incremented only once.

Does anybody know a way to work around this?

I am using this to fill up a custom nd-histogram, and obviously each bin 
should be able to get incremented more than once. Looping over the 
entire array and incrementing each bin succesively takes waaay to long 
(these are pretty large arrays, like 4000x2000 items, or even larger)


Cheers,

Vincent
