[SciPy-dev] physical quantities: udunits?
Fri Aug 1 09:28:29 CDT 2008
Here are some examples:
>>> a = unidata.udunits(1,'m')
You can also use:
Come to think of it I should change it so it only shows units compatible
Anyway, sorry I pointed to the "trunk" version, I forgot it is still
Numeric based. Or devel version is numpy based.
you can access it at:
It is indeed based on udunits (not udunits2). I should upgrade.
You're right we could probably subclass numpy. Do you want to do it?
Honestly I don't think i'll have time in the next month or so.
