Can Python Read Binary MATLAB (.mat) Files?

Reading Binary MATLAB .mat Files in Python

Python users often face the need to read binary MATLAB (.mat) files, but the availability of native support for this task is often questioned. This article addresses the question of whether it is possible to read .mat files in Python, and if so, how to accomplish it.

Utilizing SciPy for .mat File Reading

SciPy is a powerful scientific computing library for Python that includes a module for reading and writing MATLAB data files. To access this functionality, an import statement is required:

import scipy.io

Once the import is complete, the loadmat() method can be utilized to read the contents of a .mat file:

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

The mat variable will now contain a dictionary-like object with keys corresponding to the variable names stored in the .mat file and values representing the actual data.

Addressing Issues with SciPy Version 0.7.0

It is important to note that older versions of SciPy (e.g., 0.7.0) do not include the loadmat() method. If you are using an older version of SciPy, you will need to upgrade to a more recent version to take advantage of this capability.
