Documentation and usage
You can find the official documentation at:
Here is a simple example:
>>> import quantities as pq >>> distance = 42*pq.metre >>> time = 17*pq.second >>> velocity = distance / time >>> velocity array(2.4705882352941178) * m/s >>> velocity + 3 Traceback (most recent call last): ... ValueError: Unable to convert between units of "dimensionless" and "m/s"
quantities has a hard dependency on the NumPy library. You should install it first, please refer to the NumPy installation guide:
To install quantities itself, then simply run:
$ python setup.py install --user
If you install it system-wide, you may need to prefix the previous command with
$ sudo python setup.py install
To execute all tests, run:
$ python setup.py test
in the current directory. The master branch is automatically tested by Travis CI.
