MATLAB® is a programming platform designed specifically for engineers and scientists. The heart of MATLAB is the MATLAB language, a matrix-based language allowing the most natural expression of computational mathematics. UEA has a site licence, and you can run multiple instances on the cluster.
What can you do with MATLAB?
Using MATLAB, you can:
- Analyze data
- Develop algorithms
- Create models and applications
The language, apps, and built-in math functions enable you to quickly explore multiple approaches to arrive at a solution. MATLAB lets you take your ideas from research to production by deploying to enterprise applications and embedded devices, as well as integrating with Simulink® and Model-Based Design.
Using Matlab on ADA
There are two ways of working with matlab on ADA - interactive and batch mode.
Best used for testing out scripts and for jobs that require visualisation. If you need to do intensive visualisation, you should look at our visualistaion service.
- start an interactive session
- in the window (note the prompt will have changed to show the node name) type
module add matlab
- type matlab &
- then run whatever you want in matlab (using matlab help as appropriate)
- write a submit script similar to this example job script (eg matlab-test.sub):
# Mail events (NONE, BEGIN, END, FAIL, ALL)#SBATCH --mail-type=END,FAIL
# Where to send mail#SBATCH --mail-user=<username>@uea.ac.uk
#SBATCH -p compute # Select compute queue
#SBATCH -t 36:00:00 # Set time limit to 36 hours
#SBATCH --job-name=matlab-test_job # Set job name
#SBATCH -o matlab-test-%j.out # Write job output to MatJob-(job_number).out
#SBATCH -e matlab-test-%j.err # Write job error to MatJob-(job_number).err
#set up environment
module add matlab/2018a
#run the application
matlab -nodisplay -nojvm -nodesktop -nosplash -r my_matlab_m_file
- at the bottom of that script there is a line that runs your matlab commands. You can put all your matlab commands that you would type in an interactive session in a script - in the example called my_matlab_m_file
Matlab scripts - see https://www.mathworks.com/help/matlab/matlab_prog/create-scripts.html
- submit the script using sbatch matlab-submit-script-name (eg matlab-test.sub)
If you don't know how to edit files on Ada - have a look at https://rscs.uea.ac.uk/ada/using-ada/editing-files.
You might also find https://rscs.uea.ac.uk/ada/using-ada/new-to-linux useful if you aren't used to using the command line.
