Set the numeric types (real, complex, or inherited) of ports whose numeric types cannot be determined from block connectivity
#define MDL_SET_DEFAULT_PORT_COMPLEX_SIGNALS void mdlSetDefaultPortComplexSignals(SimStruct *S)
SimStruct representing an S-Function block.
The Simulink® engine invokes this method if the block has ports whose numeric types cannot
be determined from connectivity. (This usually happens when the block is unconnected or is
part of a feedback loop.) This method must set the numeric types of all ports whose numeric
types are not set. This method is only valid for simulation, and must be enclosed in a
#if defined(MATLAB_MEX_FILE) statement.
If the block does not implement this method and at least one port is known to be
complex, the engine sets the unknown ports to
COMPLEX_YES; otherwise, it
sets the unknown ports to
