(Not recommended) Set the simulation state of the C MEX S-function by restoring the SimState.

mdlSetSimState is not recommended. Use mdlSetOperatingPoint instead.

void mdlSetSimState(SimStruct* S, const mxArray* in)
S SimStruct representing an S-Function block.
const mxArray* in Any valid MATLAB data.
The Simulink® engine invokes this custom method at the beginning
of a simulation of the model containing S . Simulink
sets the initial simulation state of the S-function to the SimState
of the model.
