pause() Matlab to wait for Simulink in R2016a

Hi,

I have a Matlab script that resumes a paused Simulink simulation and waits until it pauses again. (Simulink pauses by itself using an Assertion block.) The matlab code I use is

set_param(model,'SimulationCommand','continue');
    while true
        plantStatus = get_param(model,'SimulationStatus');
        if strcmp(plantStatus,'running')
            clc
            display('waiting for Simulink to pause...')
            pause(0.1) %give thread to simulink
        elseif strcmp(plantStatus,'paused')
            %display('paused by Simulink')
            break
        end
    end

This worked fine on R2015b. On R2016a it seems as the 'while loop' is blocking Simulink from making progress in the simulation. This prevents it from reaching its pause time and therefore the Matlab loop runs forever.

To prevent Matlab from blocking Simulink, the 'pause(0.1)' statement worked before. Was its behavior changed in R2016a? Any ideas how I can fix this again?

Thanks!

Maybe the pause() function was reimplemented to allow the new pause-simulation feature in R2016a. I am just writing this to get more attention to my question ;(

I found the answer myself. I seems the problem is caused by the argument of the pause()-command. In my actual simulation (not the simple example above), the pause duration was just 500us, which worked with R2015b but not R2016a. Hence, increasing this duration to 1ms did the trick.
