I recently upgraded from version 2013 to 2014 and immediately noticed a serious degradation in the performance of my program.
Background: I had developed a specialized medical image viewer (using GUIDE) that translated mouse motion to other functionality depending on the mode the user selects. For example, if the user is in "zoom mode" then moving the mouse caused the image to zoom in & out. This is the standard/expected behavior for most programs of this type. Essentially, all I do is translate the mouse position so that it sets the xlim & ylim appropriately. (see code below)
It works well in version 2013 but is sluggish & jerky in 2014. It's almost tolerable but as my code gets more complicated the sluggishness seems to compound until the program (which works fine in 2013) is UNUSABLE in 2014.
I contacted the Mathworks. They offered a couple suggestions but basically told me that I need new hardware. Can anyone help?
I'm basically STUCK using version 2013 unless I either do a major rewrite of my program or spend a lot of money.
