Missing imports

[psychemedia]

Hi - the notebook almost but doesn't quite run on mybinder - the following bits are required:

%matplotlib inline

from numpy import ones
from matplotlib.pyplot import *

!pip install control
!conda install -y -c http://conda.binstar.org/cwrowley slycot 

ffmpeg also needs installing - which I think could be done via a Dockerfile? (The pip and conda installs could also be handled that way).

Thanks for the report. I doubt we will update this repo, as it was written to go along with a paper published 3+ years ago. You may want to track the equivalent example in the pydy repo: https://github.com/pydy/pydy/tree/master/examples/npendulum which stays up-to-date with changes in the software dependencies.

Also you can likely install ffmepg with conda: https://anaconda.org/search?q=ffmpeg
