Read .mat files in Python


An import is required, import scipy.io...

import scipy.iomat = scipy.io.loadmat('file.mat')


Neither scipy.io.savemat, nor scipy.io.loadmat work for MATLAB arrays version 7.3. But the good part is that MATLAB version 7.3 files are hdf5 datasets. So they can be read using a number of tools, including NumPy.

For Python, you will need the h5py extension, which requires HDF5 on your system.

import numpy as npimport h5pyf = h5py.File('somefile.mat','r')data = f.get('data/variable1')data = np.array(data) # For converting to a NumPy array


First save the .mat file as:

save('test.mat', '-v7')

After that, in Python, use the usual loadmat function:

import scipy.io as siotest = sio.loadmat('test.mat')
