EGI offers MATLAB on the cloud using the MATLAB Integration for Jupyter and shares data and code with other EGI users. MATLAB is also available directly on compute services offered by the members of the EGI Federation.
MATLAB on the EGI infrastructure can be used by scientists and engineers for Open Science by enabling them to share their data and code using computational notebooks.
Before getting started
To use the MATLAB Integration on the EGI Notebooks service, a supported MATLAB license is required. You can also use the toolboxes linked to your MATLAB license.
If you are unsure of your MATLAB license type, contact your System Administrator or MathWorks support.
Once your server has started up (after selecting the MATLAB environment), click on the MATLAB icon
A dialog for handling MATLAB licensing will appear.
Individual and Campus Wide MATLAB Licenses
If you have access to a MATLAB Individual License or a MATLAB Campus Wide License, use the Online License Manager tab to log in using your MathWorks account (does not need to match the email used on the EGI Identity Provider) and click on next.
If you have Network Licenses, enter the
port@hostnameof your License Server on the Network License Manager tab of the login screen. Before doing so, please check with your system administrator about allowing the EGI access to your on-prem Network License Manager (License Server).
Free trial MATLAB Licenses If you do not have a MATLAB license and would like to try it out, you can download a free MATLAB trial license here. Note that the trial license is for MATLAB only and does not have any toolboxes.
More information on MATLAB licensing with this integration can be found here.
Following this, the MATLAB IDE will appear in your browser.
To facilitate sharing your research output, you can use MATLAB Live Scripts combining rich text, equations, images, code and inline output all in one document. Live Scripts can be accessed from the Live Editor tab. Here is an example of a tutorial Live Script from the EGI webinar showing steps required to analyze some public COVID-19 data with MATLAB. Some other examples of Live Scripts can be found here.
Browser based MATLAB has some differences as compared to MATLAB on the desktop. For more information, see the limitations here. Additionally, Simulink is not supported on the EGI at this time.
Restarting, stopping or signing out of the MATLAB session
At any time, clicking on this symbol will bring up a dialog to stop, restart or sign out of the current MATLAB session.
Open Science using MATLAB on EGI Notebooks
You can access publicly available datasets via the EGI DataHub and analyze them in-the-cloud directly using MATLAB, without the need for time consuming downloads. Your MATLAB code can also be shared with your community in a variety of interoperable and open formats.
Analyzing public datasets using MATLAB on EGI
This short video and this webinar explains how to access EGI Data Services from MATLAB in detail. Data from different data providers can be accessed from the DataHub. More information on Data Management from Notebooks and persistent storage can be found here.
MATLAB support for data formats
Sharing data and code
Interoperability with Python and other languages
You can collaborate with users of other languages by calling these languages (eg. Python) from MATLAB for conducting specific analyses. You can also save data in formats compatible with other languages.
Here are some other ways in which MATLAB enables Open Science
Using MATLAB on other EGI services
In addition to MATLAB on EGI Notebooks, you can also use your MATLAB license to access MATLAB on any of the Institutions participating in the EGI Federation. To run your compute-intensive MATLAB code faster or to run code in parallel, you will need MATLAB Parallel Server and MATLAB Parallel Computing Toolbox on your MATLAB license. If you have access to a Campus Wide License , you can now scale up to use all available workers on the HPC cluster of your choice.
To access MATLAB on any site of the EGI Federation, follow these steps.
Check if you have access to MATLAB Parallel Server and Parallel Computing Toolbox
Ask the system administrator of the site about MATLAB as part of EGI
