Hi All,
Hopefully a simple newbie question, if I have an array such as :
array([0, 1, 2, 3, 4])
...what's the best way to cummulatively sum it so that I end up with:
array([0, 1, 3, 6, 10])
How would I do this both in-place and to create a new array?
cheers,
Chris

You'll have to post a traceback if we're to figure out what the problem is. A
few lines of zdum.txt would also be nice.
Suffice it to
