I recently upgraded to Matlab/Simulink 2018b on both my work machines (a Macbook with Mac OS X 10.14.2 and a desktop with Windows 7). In both machines I've experienced an unusually large number of crashes. The memory usage starts to skyrocket and I'm forced to kill the process. I've been working with Matlab/Simulink for quite some time and I've never had such a bad experience with previous versions (just in the last couple of years I worked a lot with 2018a, 2017a/b, 2016a).
I should add that the models I'm working on have been created with this new version so I can't rule out the possiblity that they are the cause of the problem. However, I'm mainly working with some simple adaptive filters implementations so I wouldn't expect the models to be the cause (especially since I have 16GB of ram in my Macbook so I wouldn't think it's that easy to crash it).
I attached the crash log I just got on my Mac, hoping it helps. As i keep working today, i'm sure I will have more logs to add to the list.
Thanks for your help.
PS: I went through other similar answers and they mention the clash between Matlab on Mac and an app call Magnet. I don't have that app installed at the moment; moreover, the problem happens also on my Windows machine.
