| Dear group,
I have written a small GUI that shows a movie frame-by-frame.
Apparently, there is a memory leak:
Starting Matlab: 300 mb of memory used
Starting my GUI and loading a 200 mb movie: 600 mb of memory used.
Everything ok till now, but then:
When I view one frame after the other, more and more memory is eaten
up, after 400 frames, 1500 mb are used (and my computer is getting
slow).
After closing the GUI, memory is back to normal.
I load the movie in OpeningFcn and make it global;
all callback functions access this global variable.
(Earlier, I saved movie in guidata, same problem.)
What is wrong here?
Any help appreciated.
I do not include the movie ;-),
but the m-file
Bye
Ben

| I think I found the solution myself:
I must cla the old plot, before I start a new one.
