Documentation

mat 7.3

Load MATLAB 7.3 .mat files into Python.

Starting with MATLAB 7.3, .mat files have been changed to store as custom hdf5 files. This means they cannot be loaded by scipy.io.loadmat any longer and raise.

NotImplementedError: Please use HDF reader for matlab v7.3 files

Quickstart

This library loads MATLAB 7.3 HDF5 files into a Python dictionary.

import mat73
data_dict = mat73.loadmat('data.mat')

As easy as that!

Installation

To install, run:

pip install mat73

Alternatively:

pip install git+https://github.com/skjerns/mat7.3

Short-comings

  • This library will only load mat 7.3 files. For older versions use scipy.io.loadmat
  • cell objects are loaded as lists. That means they lose their structure and and need to be sorted manually
  • Proprietary MATLAB types (e.g datetime, duriation, etc) are not supported. If someone tells me how to convert them, I'll implement that
  • For now, you can't save anything back to the .mat
