Persistent variable clear after simulation with simulink

Hello, i have a problem, where I need help. I have decleared and initilized a persistent variable var in a Matlab Embedded Function in Simulink. For example

persistent var
if isempty(var)
  var= 1
end

I noticed that the variable doesn't exist after the simulation end's. Thats why var is initialized again, when i start a simulation. Is this normal ? (I don't have any function in Model Property)

Yes. This is normal.

The persistent variable will persist between time steps of the simulation, i.e., between calls to the MATLAB Function. At the end of simulation, the variable will go out of scope.

What exactly are you trying to do between simulations with such a variable? Maybe there's another way.

I would gather from this that a "clear" is being one at some point ?

Though if it is one of the Accelerator modes then you are probably running a complete executable...

No i tested it with a model only with this code in a Matlab Embedded Function
