How to read a .mat (MATLAB) file in Python


In order to read a .mat Matlab file from your Python code, you can make use of the scipy.io module.

This module contains scipy.io.loadmat() method which you can use to load a .mat file.


Example with spicy.io module:

import scipy.io

my_matlab_file = scipy.io.loadmat('my_matlab_file.mat')


patient = my_matlab_file['patient']
infection = my_matlab_file['infection']
treatment = my_matlab_file['treatment']

print(patient)
print(infection)
print(treatment)

Note: To read MATLAB 7.3 file formats you will need HDF5 Python library.



Example with h5py module:

import h5py

my_matlab_file = h5py.File('my_matlab_file.mat', 'r')

data_x = my_matlab_file['data_x']
data_y = my_matlab_file['data_y']
