Essentially, the code you sent is merely a wrapper around 'histc'. It
seems that 'histc' does not support weights, so I don't think the
changes will be trivial. I think the 'histc' API could be extended to
support optional weights, but that would need some discussion.

Alternatively, you might be able to use that 'histc' can optionally
return the histogram indexes. From these you should be able figure out
which weights should be added together. I know this a vague description,
but it might get you in the right direction.
