Overview

This repo is a tutorial comparing Matlab and numpy (a python library) in signal analysis. Data and Matlab code obtained from the lecture of Dr Chia-Feng Lu. The corresponding python code is provided to help readers to learn how to use free numpy, scipy and scikit-learn library in python to conduct signal analysis tasks.

You can click to open the notebook of the python version in Colab and exclude the code there directly.

How to Use Jupyter nootbook with matlab

1. install python, matlab

The matlab software and Python need to be installed.

matlab currently only supports python 3.8 and below

2. install matlab_kernel

pip install matlab_kernal

3. Configure matlab_kernal

1. cd to the Matlab installation directory (C:\Program Files\MATLAB for Windows)
2. cd to MATLAB\(current version directory)\extern\engines\python
3. execute the python setup.py install command

4. install jupyter notebook or jupyter lab

pip install notebook

5. Start jupyter notebook

jupyter notebook

If you open jupyter notebook in your browser and select malab in the kernel, you can use matlab in jupyter notebook just like python.
