IO Utilities
============

Routines for reading and writing demand modelling files, particularly matrices and TMGToolbox network packages.

Matrices
--------

Common
~~~~~~

.. automodule:: balsa.routines.io.common

Inro (Emme) format
~~~~~~~~~~~~~~~~~~

.. automodule:: balsa.routines.io.inro

OMX format
~~~~~~~~~~

The Python library openmatrix already exists, but doesn't provide a lot of interoperability with Pandas. Balsa provides
wrapper functions that produce Pandas DataFrames and Series directly from OMX files.
