University Purchases Three-Year Site License for MATLAB Software

Mathworks LogoStony Brook University purchased a three-year site license for MATLAB softwareSimulink, and companion toolboxes from Mathworks. The new license agreement began Aug. 1, and covers installation of the software on University-owned computers (including classrooms and labs), as well as home use (one installation on a personal computer per person) for all instructors, students, staff, and researchers.

Please visit the MATLAB software page for instructions on how to obtain the software. Users must create a Mathworks account and activate the software before downloading and installing it on their computers.

Stony Brook University’s campus license includes the following standard MATLAB toolboxes:

  • Bioinformatics Toolbox

  • Control System Toolbox

  • Curve Fitting Toolbox

  • Data Acquisition Toolbox

  • DSP System Toolbox

  • Image Processing Toolbox

  • Instrument Control Toolbox

  • MATLAB

  • Optimization Toolbox

  • Parallel Computing Toolbox

  • Signal Processing Toolbox

  • SimMechanics

  • SimScape

  • Simulink

  • Simulink Control Design

  • Stateflow

  • Statistics Toolbox

  • Symbolic Math Toolbox

Additional toolboxes may be purchased as child licenses of the MATLAB TAH license by contacting Debbi Cohen at Mathworks.

As a service to the Stony Brook community, a MATLAB listserv has been established as a way for users of this software to ask each other questions, develop solutions, and share information. The list is open to all subscribers with @stonybrook.edu and @stonybrookmedicine.edu email addresses.

To subscribe to the list, send an email to listserv@lists.sunysb.edu with the following information in the body:

  • SUBSCRIBE matlab-l FirstName LastName (replace FirstName and LastName with your own full name)

Once you are subscribed to the list, you can post questions to the community by emailing matlab@lists.sunysb.edu

MATLAB will be visiting Stony Brook University in early October to give some presentations on its products and to answer questions from the community. A separate event invitation will be distributed once a date has been scheduled.

For questions about the license agreement and what it entitles you to, please contact DoIT’s Research Technologies team at researchtech@stonybrook.edu. The Client Support Help Desk can assist with technical questions related to downloading, installing, and configuring the software. Client Support can be reached at (631) 632-9800 or by emailing supportteam@stonybrook.edu.

Internet Connectivity Restored

Update:  Aug. 13, 12:32 p.m. – WolfieNet-Guest Wi-Fi Access Restored

WolfieNet-Guest is now operational after one of Stony Brook’s internet service providers was brought back online.

Update:  Aug. 13, 11:30 a.m. – All Services Restored Except for WolfieNet-Guest

Stony Brook guests are currently unable to connect to the WolfieNet-Guest Wi-Fi network as part of a lingering effect of yesterday’s wide-spread Internet connectivity issues. DoIT’s Data Network Services team is actively working to bring this service back up.

Yesterday, Stony Brook University users may have noticed inconsistencies while browsing certain websites as well as six 2-3 minute outages while DoIT’s networking team worked with SB’s internet service providers (IPS’s) to restore services by switching over to SB’s secondary and tertiary network providers.

The initial problem was caused when a flood of new routes were advertised on the Internet. These new routes brought the number of total routes over 512k which is the routing table limit for many Internet routers, creating problems for most of the major ISP’s in North America. Once Stony Brook realized there were problems with its primary ISP, it switched over to its secondary ISP and when that did not remediate the problem, it then had to turn to its tertiary ISP. Switching to its tertiary ISP resolved most of the problems that end users were experiencing.

The remaining browsing problems people were still experiencing were triggered by the initial routing advertisement which cascaded down to the campus border router bringing its table beyond capacity and causing it to act erratically in routing traffic to the Internet. Once Stony Brook rebooted its hardware at 8:15 p.m. all traffic then began routing as expected.

Here is a further description of the root cause of yesterday’s issues and its impact across the Internet: http://www.zdnet.com/internet-hiccups-today-youre-not-alone-heres-why-7000032566/

Update:  Aug. 12, 8:40 p.m. – All Services Restored

A flood of new networking routes overwhelmed internet service provider (ISP) routers, which caused multiple service disruptions throughout the day on Aug. 12. Stony Brook’s Data Network Services team, working with SB’s internet service providers, have since resolved all issues. All systems (DoIT websites, including the IT System Status page, SOLAR, Blackboard, as well as other Stony Brook sites) should now be fully accessible from both on and off campus.

Update: Aug. 12, 8:12 p.m. – Network Outage beginning 8:15 p.m. 

Due to severe internet traffic issues today that are beyond our control, we are forced to take down our primary router for a period of 10-15 minutes starting at 8:15pm. This means people outside of the Stony Brook campus network will not be able to reach our websites. It also means people inside the Stony Brook network will not be able to access websites off campus. Users on campus should be able to reach most Stony Brook websites.

Stony Brook University is currently experiencing network-based Internet access issues for both on and off campus users. Users have reported they have inconsistent access to DoIT web sites (including IT System Status), SOLAR, Blackboard, as well as other Stony Brook sites.

We are working closely with our internet service providers to resolve the problem. Status updates will be provided on the IT Status site for those who can access it (http://it.stonybrook.edu/status) and at the SBUDoIT Twitter feed (https://twitter.com/sbudoit).
