Hi Johan,
Thanks for your quick response.
It is Matlab System Error. I attached the crash report.
I added sdpsettings('debug',1) to my program, but it does not change any,
maybe because that command line cannot be finished.
When Matlab crashes, the command window shows
------
SeDuMi 1.3 by AdvOL, 2005-2008 and Jos F. Sturm, 1998-2003.
Alg = 2: xz-corrector, theta = 0.250, beta = 0.500
----
and stay busy.
Crash occurs within a second when the program reaches at ``solvesdp''.
