flowdyn.monitors

module monitors

This module implements generic monotoring of iterative integration. Specific implementation is done in flowdyn.integration. A monitor directive is passed to *.solve integration as a dictionary with its own parameters. A monitor class is returned with 'output' key.

Example:

    $ python example_google.py
