MATLAB

Introduction

MATLAB -- MATrix LABoratory -- is an integrated and extensible, technical computing environment that delivers powerful computation, visualization, and application development tools to your desktop.

The CSE department makes MATLAB available for research purposes on departmental Linux hosts, and for instructional purposes on a subset of the department's instructional Linux and Windows hosts.

Research Usage

MATLAB is available on lab-managed Linux hosts through /projects/matlab. Our research licenses are part of a centrally-administrated campus pool, run by the College of Engineering.

Before using MATLAB, you must define an environment variable called MLM_LICENSE_FILE with the following value:
27000@lmas.engr.washington.edu,27000@nexus.engr.washington.edu,27000@persephone.engr.washington.edu.
This environment variable is used by MATLAB to acquire a license for your use of the software.

Our department's MATLAB installation includes twenty (20) licenses for the MATLAB application, and the following license quantities for MATLAB toolboxes:

  • Control System Toolbox (10)
  • Image Processing Toolbox (10)
  • Mapping Toolbox (10)
  • MATLAB Compiler (2)
  • Neural Network Toolbox (5)
  • Optimization Toolbox (10)
  • Partial Differential Equation Toolbox (10)
  • Robust Control Toolbox (10)
  • Signal Processing (20)
  • Simulink (10)
  • Statistics Toolbox (10)
  • System Identification Toolbox (10)
  • Wavelet Toolbox (10)

Instructional Usage

MATLAB is available in the basement labs (002, 006, and 022) on Windows and Linux machines. From a Windows host, access MATLAB through the Start menu. From a Linux host, MATLAB is available through /projects/instr/matlab.

This instructional installation has twenty-one licenses, and only the basic MATLAB application is available -- no toolboxes.

Troubleshooting

If you start MATLAB and an error message similar to this appears, it means that all of our MATLAB licenses are in use.

License checkout failed.
License Manager Error -87
Checkout exceeds MAX specified in options file.
Contact your License Administrator to review the Options File.
When this happens, wait a little while and try accessing MATLAB again. If you're curious to see who has MATLAB licenses checked out, the following command will produce a list of MATLAB users currently using one or more licenses from the centrally-administered pool:
cd /projects/matlab/etc/glnxa64
./lmutil lmstat -a | less
From this list, searching for cs.washington.edu hostnames will reveal who is using licenses from the department's share of the pool.

If this problem persists for more than a few hours, please contact CSE Support.

Documentation on MATLAB is available from the Mathworks site.

Personal Use

Enrolled students can purchase MATLAB from the University Bookstore to install on their personal computers (Macintosh or Windows).

Faculty and graduate students who would like a copy of MATLAB installed on their own computer can order MATLAB through the College of Engineering.
