mdlSetInputPortComplexSignal (Writing S-Functions)

Set the numeric types (real, complex, or inherited) of the signals accepted by an input port

C Syntax

void mdlSetInputPortComplexSignal(SimStruct *S, int_T port, 
CSignal_T csig)

C Arguments

S
SimStruct representing an S-Function block.

port
Index of a port.

csig
Numeric type of signal.

M Syntax

SetInputPortComplexSignal(s, port, typeId)

M Arguments

s
Instance of Simulink.MSFcnRunTimeBlock class representing the S-Function block.

port
Integer value specifying index of port to be set.

typeId
Integer value specifying whether the port accepts real (0) or complex (1) signals.

Description

Simulink calls this routine to set the input port signal type. The S-function must check whether the specified signal type is a valid type for the specified port. If it is valid, the S-function must set the signal type of the specified input port. Otherwise, it must report an error using ssSetErrorStatus. The S-function can also set the signal types of other input and output ports with unknown signal types. Simulink reports an error if the S-function changes the signal type of a port whose signal type is known.

If the S-function does not implement this routine, Simulink assumes that the S-function accepts a real or complex signal and sets the input port signal type to the specified value.
