S-Function - share complex variable between method functions

Hello,
I'm trying to implement an MPC controller in simulink using Yalmip.
I'm a bit stuck because i need to pass a complex (non-default type) variable / object between the Start function, which initializes the optimization object, and the Output function which then computes the controller command using the optimizer object.
Is there any method to pass variables / objects between functions? I don't think i can use the s-function states due to the variable type.
Thanks, Alex

If you are writing a C-MEX S-function, you can do this using a PWork vector. Please see the following links for help:
If you are writing a Level-2 MATLAB S-function, this is not very straightforward, but I explained here how you can use the block's UserData to achieve this.
