(Not recommended) Return the C MEX S-function simulation state as a valid MATLAB data structure, such as a matrix structure or a cell array.
Note
mdlGetSimState is not recommended. Use mdlGetOpeartingPoint instead.

#define MDL_SIM_STATE
mxArray* mdlGetSimState(SimStruct* S)
S SimStruct representing an S-Function block.
The Simulink® engine invokes this custom method to get the
simulation state (SimState) of the model containing S.
A call to this method should occur after mdlStart and
before mdlTerminate to ensure that all of the S-function
data structures (e.g., states, DWork vectors, and outputs) are available.
