MATLAB Introduction The Johns Hopkins University has licensed MATLAB and several toolboxes for use across the University using concurrent (network) licensing. This means that a client computer (UNIX, PC, Mac OS X) running MATLAB checks against a common license server in order to keep JHU within compliance of our license agreement. Note: all computers must reside on the JHU Campus Network and must be registered with our license servers in order to use MATLAB and the toolboxes. If you are using a laptop or need to use MATLAB when disconnected from the JHU Campus Network, you should consider a standalone MATLAB license instead. License Agreement The "All Platform" workstation site license covers: - cover UNIX workstations and networked PCs on JHU Campus Network
- allow a maximum of 150 user keys for MATLAB, SIMULINK, and three MATLAB Application Toolboxes:
- Signal Processing
- Optimization
- Neural Networks
- an additional 50 user keys would be obtained for each of the following MATLAB Application Toolboxes:
- Systems Identification
- Image Processing
- control Systems
- Statistics
- Simulink Control Design
Finally, trade-ins from existing site id holders and individual purchases will add licenses for the following MATLAB Application toolboxes. These will only be available to specific groups. - Symbolic Math
- Compiler
- Wavelet
- Database
- Spline
- Virtual Reality
Access to MATLAB, SIMULINK, and the Application Toolboxes on these workstations is provided through a Floating Network License, managed by three (3) centrally-located license servers. This means when you invoke MATLAB on your local computer, it will contact one of the license servers to obtain a "user key".License Server Maintenance In an effort to allow timely updates to host lists (machines allowed to use MATLAB) while minimizing downtime, we are proposing license server changes and restarts twice a month. We have picked the FIRST and THIRD THURSDAYs of the month at 8:30am to restart the license servers. The license servers should be down no longer than 10-15 minutes. By scheduling these server changes, we hope to minimize inconvenience to people running long MATLAB jobs.
