I have an Interpreted matlab function block in my simulink file which solves a MPC problem everytime it is called. I am using YALMIP and I wish to setup the 'optimizer' variable in a PostLoad Fcn, as setting it up at every time instant has huge overhead. I want to call the 'optimizer' variable in my interpreted matlab function block to solve the MPC problem. Intially I thought of creating a persistent variable and setting it up within the Interpreted function, but this would mean that it will take a long time before I can return my first control command, this will cause it to miss the deadline to produce the control command.

Is there a way in which I can call this variable from the workspace, in a manner similar to "Paramter Data" in normal Matlab function blocks?
