mdlSetDefaultPortComplexSignals

Set the numeric types (real, complex, or inherited) of ports whose numeric types cannot be determined from block connectivity

Required

No

Languages

C, C++

Syntax

#define MDL_SET_DEFAULT_PORT_COMPLEX_SIGNALS
void mdlSetDefaultPortComplexSignals(SimStruct *S)

Arguments

S

SimStruct representing an S-Function block.

Description

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 COMPLEX_NO.
