Writing S-Functions

ssSetVectorMode

Specify the vector mode that an S-function supports.

Syntax

void ssSetVectorMode(SimStruct *S,  ssVectorMode mode)

Arguments
S
   SimStruct representing an S-function block.

Description

Specifies the types of vector-like signals that an S-function block's input and output ports support. Simulink uses this information during signal dimension propagation to check the validity of signals connected to the block or emitted by the block. The enumerate type, ssVectorMode, defines the set of values that mode can have.

Mode Value	Signal Dimensionality Supported
SS_UNKNOWN_MODE	Unknown
SS_1_D_OR_COL_VECT	1-D (vector) or single-column 2-D (column vector)
SS_1_D_OR_ROW_VECT	1-D or single-row 2-D (row vector) signals
SS_1_D_ROW_OR_COL_VECT	Vector or row or column vector
SS_1_D_VECT	Vector
SS_COL_VECT	Column vector
SS_ROW_VECT	Row vector
