ssGetBusElementDimensions
Get the dimensions of a bus element
Syntax
const int_T* ssGetBusElementDimensions(SimStruct* S, int_T busTypeID, int_T elemIdx)
Arguments
S
SimStruct that represents an S-Function block
busTypeID
The bus data type identifier that represents the bus signal
elemIdx
The zero-based bus element index
Returns
const int_T*
Description
Obtain the dimensions (const int_T*
) for the bus element that
you specify. To iterate over the integer array that
ssGetBusElementDimensions
returns, use ssGetBusElementNumDimensions
.
Languages
C, C++
Examples
static void mdlOutputs(SimStruct *S, int_T tid) { DTypeId dType = ssGetOutputPortDataType(S, 0); const void *u = ssGetInputPortSignal(S, 0); int numElems = ssGetNumBusElements(S, dType); int i; for(i=0; i<numElems; i++) { int_T numDims = ssGetBusElementNumDimensions(S, dType, i); const int_T *dims = ssGetBusElementDimensions(S, dType, i); int width = 1; int j; /* Compute width of the bus element */ for(j=0; j<numDims; j++) { width *= dims[j]; } } }
