Specify that an input port expects zero-based indices
void ssSetZeroBasedIndexInputPort(SimStruct *S, int_T pIdx)
SimStruct that represents an S-Function block.
Input port of the S-function.
Use this macro in
mdlInitializeSizes to specify that
pIdx expects zero-based index values. By setting this macro,
the Simulink® engine runs a diagnostic when it updates the diagram to check if the
S-function input port expecting zero-based indices is connected to a block that is
producing one-based indices. The engine signals an error if it detects that the
signal connected to this block is one-based. Simulink blocks that can produce indices include the For Iterator and
S-function blocks. If neither this macro nor
invoked, The engine does not run this diagnostic, even if the input port is
connected to a block that produces indices.
