From: Michael Giacomelli on 18 Jan 2010 17:56 Hi. Whenever I try to do image or surf, there is about a 1 in 10 chance that matlab will simply close with the standard windows "this program has encountered an error" dialog. I suspect opengl problems based on google results, but no suggested fixes work for me. I am running matlab 2009a and 2009b on a Windows 2008R2 64 bit work station with an Nvidia GTS250 GPU. Both have the same problem. I've the latest drivers (195.62_desktop_win7_winvista_64bit_english_whql), but my problems occur with all driver versions I have tested. The system is otherwise completely stable (runs my fortran code for weeks at a time and all GPU intensive programs I use report no trouble). Is there some way to debug this? I can't locate any error logs, and that mathworks support docs don't turn up anything at all on my problem. Mike

It still readily crashes after a few imagesc calls. >...Just curious, how big is the matrix you are trying to visualize? 100x100 pixels.

It still readily crashes after a few imagesc calls. Fine! Then it is not the OpenGL part - which is subject to a pile of scary problems. Can you post your program? Jan |
