Matlab GUI figure axes goes blank after using slider ca. 20 times.

Hi.

I have written a code for a GUI figure that creates a contour using sliders.

The first problem was that after running the callback function a few times (ca. 20-50), all the contours from the previous inputs would overlap, filling the axes with what looked like random colours and lines.

I managed to prevent this by clearing the axes at the beginning of the function so that a new contour is created every time.

But that solution only changed the bug. Now, after running it 20-50 times the axes just goes blank.

Unfortunately, I am having trouble connecting to the network drive the figure is stored on right now, so I cannot post excerpts from the code. I will do this once I get connected.

Has anyone had the same problem before and found a solution or is this a Matlab bug? The exported standalone version has the same bug.

Thanks!

Marc

Just found a variable that does not get defined at a certain value of one of the sliders. Making sure it always gets defined seems to have fixed the problem.

I'll post again if it persists.
