Hi Yan Zhang,
the GAC and the hybrid model does not work anymore. I changed my environment to windows 7 (64bit). When I run the examples in ac_GAC_model.m and ac_hybrid_model.m, I get the following error message: "MATLAB has encountered an internal problem and needs to close".
Everything works fine on Mac and 32bit Windows. The crash_dump says a "Segmentation violation detected" in ac_tridiagonal_Thomas_dll.mexw64.
Has anyone else this error?
