Description
MATLAB is a high-level language and interactive environment for numerical computation, visualization, and programming. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation.
Key capabilities:
Numerical computation and matrix operations
Advanced plotting and data visualization
Built-in toolboxes for signal processing, machine learning, optimization, and more
Supports parallel and GPU computing
Used across engineering, scientific research, and industry
MATLAB: Run MATLAB from the Loki cluster over an SSH tunnel Provides guidance for launching MATLAB on the Loki cluster with X11 forwarding over SSH, enabling graphical interface access from your local workstation.
Note
For graphical MATLAB sessions, see matlab.

-h|-help - Display arguments.
-n - Display final environment variables,
arguments, and other diagnostic
information. MATLAB is not run.
-e - Display ALL the environment variables and
their values to standard output. MATLAB
is not run. If the exit status is not
0 on return then the variables and values
may not be correct.
v=variant - Start the version of MATLAB found
in bin/glnxa64/variant instead of bin/glnxa64.
-c licensefile - Set location of the license file that MATLAB
should use. It can have the form port@host or
be a colon separated list of license files.
The LM_LICENSE_FILE and MLM_LICENSE_FILE
environment variables will be ignored.
-display Xdisplay - Send X commands to X server display, Xdisplay.
Linux only.
-nodisplay - Do not display any X commands. The MATLAB
desktop will not be started. However, unless
-nojvm is also provided the Java virtual machine
will be started.
-noFigureWindows - Disables the display of figure windows in MATLAB.
-nosplash - Do not display the splash screen during startup.
-softwareopengl - Force MATLAB to start with software OpenGL
libraries. Not available on macOS.
-nosoftwareopengl - Disable auto-selection of software OpenGL
when a graphics driver with known issues is detected.
Not available on macOS.
-debug - Provide debugging information especially for X
based problems. Linux only.
-desktop - Allow the MATLAB desktop to be started by a
process without a controlling terminal. This is
usually a required command line argument when
attempting to start MATLAB from a window manager
menu or desktop icon.
-nodesktop - Do not start the MATLAB desktop. Use the current
terminal for commands. The Java virtual machine
will be started.
-singleCompThread - Limit MATLAB to a single computational thread.
By default, MATLAB makes use of the multithreading
capabilities of the computer on which it is running.
-nojvm - Shut off all Java support by not starting the
Java virtual machine. In particular the MATLAB
desktop will not be started.
-jdb [port] - Enable remote Java debugging on port (default 4444)
-batch MATLAB_command - Start MATLAB and execute the MATLAB command(s) with no desktop
and certain interactive capabilities disabled. Terminates
upon successful completion of the command and returns exit
code 0. Upon failure, MATLAB terminates with a non-zero exit.
Cannot be combined with -r.
-r MATLAB_command - Start MATLAB and execute the MATLAB_command.
Cannot be combined with -batch.
-sd folder - Set the MATLAB startup folder to folder, specified as a string.
Cannot be combined with -useStartupFolderPref.
-useStartupFolderPref - Set the MATLAB startup folder to the value
specified by the Initial working folder option
in the General Preferences panel.
Cannot be combined with -sd.
-logfile log - Make a copy of any output to the command window
in file log. This includes all crash reports.
-Ddebugger [options] - Start debugger to debug MATLAB.
-nouserjavapath - Ignore custom javaclasspath.txt and javalibrarypath.txt files.
Examples/Usage
Load the MATLAB module:
$ module load math/MATLAB/2021a_u3
Unload the module:
$ module unload math/MATLAB/2021a_u3
Start MATLAB with full desktop environment:
$ matlab
Run MATLAB in command-line (non-GUI) mode:
$ matlab -nodesktop -r "disp('Hello from MATLAB'); exit"Run a MATLAB script non-interactively:
$ matlab -nodesktop -r "run('my_script.m'); exit"
