ssSetOutputPortComplexSignal (Writing S-Functions)

Set the numeric type (real or complex) of an output port.

Syntax

void ssSetOutputPortComplexSignal(SimStruct *S, input_T port, 
CSignal_T csig)

Arguments

S
SimStruct representing an S-Function block or a Simulink model.

port
Index of an output port.

```
csignal
```

Numeric type of the signals emitted by port. Valid values are COMPLEX_NO (real signal), COMPLEX_YES (complex signal), and COMPLEX_INHERITED (dynamically determined).

Description

Use this function in mdlInitializeSizes to initialize an input port signal type. If the numeric type of the input port is determined dynamically, e.g., by a parameter setting, set the numeric type to COMPLEX_INHERITED. The default numeric type of an output port is real.

Languages

Example

Assume that an S-function has three output ports. The first output port emits real (noncomplex) signals. The second input port emits a complex signal. The third port emits signals of a type determined by a parameter setting. The following example specifies the correct numeric type for each port.

ssSetOutputPortComplexSignal(S, 0, COMPLEX_NO)
ssSetOutputPortComplexSignal(S, 1, COMPLEX_YES)
ssSetOutputPortComplexSignal(S, 2, COMPLEX_INHERITED)
