I am working on project which involve image processing on video files.All my codes are working fine.But,sometimes,when i am executing my program,matlab and my system hangs and program stop responding to my commands.I suspect it may be due to main memory getting overloaded.Is there any way,in which i can keep flushing main memory as one action is completed?

"clear" variables when you are finished using them.

If you are using virtual memory or swap space, you might want to reduce that so that the program runs out of memory and gives an error instead of using the (very slow) disc as memory.

Thanx Walter for ur response.I am using GUI in which I am reading avi file and then reading consecutive frames and calculating Frame diff to check for intrusion.This is in loop till end of file or user interrupts. how to clear the variables wen i m still using them?

[Walter Roberson]

newframe = get first frame

while true

oldframe = newframe;

newframe = get another frame

do the frame difference

clear oldframe

end

clear newframe
