Subject: MATLAB is not working: "Licence checkout failed" 

For some unknown to me reason,

Matlab stopped working about 20 minutes ago on all computers in the control room (both UNIX control machines and Windows).

It says: "License checkout failed. License Manager Error -15. MATLAB is unable to connect to the license server."

I do not know how to revive Matlab.

At the same time, I consider that I made a significant progress in building my theoretical/computational model in the last 2 days. I was able to compute the time-evolution of accelerometer signals through stacks and pendulums using Matlab command "lsim", and I am now able to calculate RMS of spectrum of differential arm length in different frequency intervals. It seemed to me that everything is ready in my program to make the three-dimensional theoretical/computational plot (RMS as a function of Q-factors of ETMX and ITMX), but unfortunately Matlab stopped working. It seemed to me that all that was remaining was to run a loop with all possible values of Q-factors. Let's hope that Matlab will be working after the weekend.

Andrey.
