Hi Anne, Thanks for your reply. As you say there are a few different problems in here. The first is about implementing a system of physical quantities with units. I reviewed various options for this including the ones you mentioned (unum and ScientificPython), but they all had some important featu

[Numpy-discussion] Proxy array class and units

2008-02-13 Thread Dan Goodman
Hi all, I'm looking for some advice on how to implement a 'unit checking proxy array'. Background: I'm writing a package to run simulations which make extensive use of linear algebra, for which I'm using numpy. However - it is important to my package that quantities can have dimesions, so I've w
