The message is as below: Configuration: Crash Decoding : Disabled Default Encoding: windows-1252 MATLAB Root : G:\Program Files\MATLAB\R2012a MATLAB Version : 7.14.0.739 (R2012a) Operating System: Microsoft Windows 7 Processor ID : x86 Family 6 Model 42 Stepping 7, GenuineIntel Virtual Machine : Java 1.6.0_17-b04 with Sun Microsystems Inc.
