ssSetInputPortVectorDimension

Specify dimension information for an input port that accepts vector signals

Syntax

int_T ssSetInputPortVectorDimension(SimStruct *S,  int_T port,
 int_T w)

Arguments

S

SimStruct representing an S-Function block.

port

Index of an input port.

w

Width of the vector or DYNAMICALLY_SIZED.

Returns

1 if successful; otherwise, 0.

Description

Specifies that port accepts a w-element vector signal. If the width is dynamically sized, the S-function must provide mdlSetInputPortDimensionInfo and mdlSetDefaultPortDimensionInfo methods to enable the signal dimensions to be set correctly during signal propagation.

Note

This function and the ssSetInputPortWidth macro are functionally identical.

Languages

C, C++

Example

The following example specifies that input port 0 accepts an 8-element matrix signal.

ssSetInputPortVectorDimension(S, 0, 8);
