INSTALLATION

To download this library, click on the green dropdown box that says "Code" and click on "Download ZIP". Once the ZIP file has downloaded, you will have to extract the files from that ZIP folder. Once the files are extracted, they will be available for your use.

MATLAB VERSION

There are no known incompatibilities using MATLAB version R2019a.

MATLAB Toolboxes Required:

Statistics and Machine Learning Toolbox

Signal Processing Toolbox

Image Processing Toolbox

Parallel Computing Toolbox

Application Compiler Toolbox

PYTHON VERSION

To install from the requirements.txt file, make sure you have the package installer for Python (pip) on your PATH, and use the following command:

pip install -r requirements.txt

If you are installing using pip3, then simply use the command:

pip3 install -r requirements.txt

After installing these libraries, the Python scripts are available for use.
