Hi, I have a conceptual question:
I'm creating a simulink block using a Level-2 MATLAB S-function, I need the Start function to create an object (variable1 for example), which must keep existing until the Terminate function clears it.
This variable1 object must be accessed from all the other functions called by the block, like the Output function that calculates the value of the output port of my block (I only have one), so my solution was to declare this variable1 object as global.
Is there any way to make the object exist only inside the workspace of the block I am creating, and be shared only between the registered functions of the level-2 MATLAB S-function, so I can avoid to make it global?
Thanks in advance for the answers!

Hi,
I´m not sure if this is what you meant, but using a DWork vector should solve your problem.
Like stated in the link below, the DWork vector stores the discrete information of your variable through all functions in your
S-Function.
Regards.
