Import and Read .mat File in Python

option to save the .mat file in an older file format. This can be easily read by python with the following script. Make sure the mu.mat file is inside the same folder as this script:

import scipy.io as sio
muf = sio.loadmat('mu.mat')
mu = muf.get('mu')
mu = mu.flatten()
print(mu)

There are other questions regarding the standard .mat file format from MATLAB, this you can find here: StackOverflow read .mat files. Here someone suggested to use a custom written package for python called 'mat73'.

In general .mat files are an variation of the well known HDF file format so with the latest version of a HDF5 reader and the latest .mat file version, there are very likely other options to import .mat files in different programming languages than the one that I present here.

Thanks for the quick reply @mbvoyager. Does this also work for .mat/mldatx files that contain TimeSeries data? This would typically be output/log from Simulink runs. I tried to use 'hf5py' module, but was unable to read TimeSeries data stored in a .mat file. Scipy seems to work well for cases when Maltab workspace is saved to .mat file.
