Specify the vector mode that an S-function supports
void ssSetVectorMode(SimStruct *S, ssVectorMode mode)
Specifies the types of vector-like signals that an S-Function block's input and output ports support. The Simulink® engine uses this information during signal dimension propagation to check the validity of signals connected to the block or emitted by the block. The enumerated type ssVectorMode defines the set of values that mode can have.
Signal Dimensionality Supported
1-D (vector) or single-column 2-D (column vector)
1-D or single-row 2-D (row vector) signals
Vector or row or column vector
