Set the numeric types (real, complex, or inherited) of the signals accepted by an output port
No
C, C++
#define MDL_SET_OUTPUT_PORT_COMPLEX_SIGNAL
void mdlSetOutputPortComplexSignal(SimStruct *S, int_T port,
CSignal_T csig)
S SimStruct representing an S-Function block.
port Index of a port.
csig Numeric type of signal, either COMPLEX_NO (real)
or COMPLEX_YES (complex).
The Simulink® engine calls this routine to set the output
port numeric type for outputs that have this attribute set to COMPLEX_INHERITED.
The input argument csig is the proposed numeric
type for this output port. The S-function must check whether the specified
numeric type is a valid type for the specified port.
If it is valid, C MEX S-functions set the numeric type of the
specified output port using ssSetOutputPortComplexSignal.
Otherwise, the S-function reports an error, using ssSetErrorStatus#if defined(MATLAB_MEX_FILE) statement.
The S-function can also set the numeric types of other input and output ports with unknown numeric types. The engine reports an error if the S-function changes the numeric type of a port whose numeric type is known.
If the S-function does not implement this routine, the engine assumes that the S-function accepts a real or complex signal and sets the output port numeric type to the specified value.
The engine calls this method until all output ports with inherited numeric types have their numeric types specified.
