A network license (a.k.a.concurrent license) is operated by the College of Engineering and paid for using Technology Fee funds. In order to use this Matlab, you need to be on a Georgia Tech owned machine that can talk to the campus license server. Typically, this means the system is on the Georgia Tech network in an office or lab, or on the campus VPN. Netowrk licensed systems can access Matlab and a large selection of toolboxes.
To use a network license, download Matlab installers from software.oit.gatech.edu. Follow the directions to point your systems at the campus license server license.gatech.edu.
