Matrix Converters

This package bundles functions which read and write various matrix file formats using nothing but the Scientific Python stack (NumPy and Pandas). The idea is to allow closed-source software (e.g. Emme, VISUM, Cube, etc.) to "talk" to each other through matrices.

Each format comes with a reader and writer, which converts to and from NumPy arrays or Pandas DataFrames. Pandas Series with 2-level MultiIndex are also supported.
