Alternatives

MATLAB is vendor-specific, and comparably expensive licensed software and thus not generally available. Consider using an unencumbered alternative solution.

Octave

If you have existing MATLAB code, try running in using GNU Octave instead of MATLAB for all but the most demanding or vendor-specific tasks:

  • To start octave:
octave

Python or Perl

For more flexibility, use a general-purpose scripting language.

Licensing

MATLAB is available on Carbon on request, and is subject to strictly limited license terms. Running MATLAB is restricted to:

  • Argonne employees (including consultants and students),
  • by one user at a time.

Toolboxes

We have the following toolboxes installed:

  • Curve Fitting Toolbox
  • Image Processing Toolbox
  • Optimization Toolbox
  • Parallel Computing Toolbox
  • Statistics Toolbox


Running MATLAB

  • To get started, load the "matlab" module as described at HPC/Module Setup.
  • Then choose how to run the application:
GUI
matlab
Command line
For basic calculations, you could save some startup time by simply using the text interface.
matlab -nojvm
Does not load the Java VM and toolboxes requiring any java.

or

matlab -nodisplay
Suppresses X11.

Troubleshooting

Access

To run MATLAB on Carbon, you must be a member of the "employees" group. You could still load the "matlab" module if you are not, but it will not enable anything.

  • To inspect your current group membership, run:
groups
The word "employees" must show.


License in use

License checkout failed.
License Manager Error -9
This error may occur when:
-The hostid of this computer does not match the hostid in the license file.
-A Designated Computer installation is in use by another user.
If no other user is currently running MATLAB, you may need to activate.
