ssGetBusElementNumDimensions
Get the number of dimensions for a bus element
Syntax
int_T ssGetBusElementNumDimensions(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
int_T
Description
Get the number of dimensions for the bus element that you specify. Use the
returned value to loop over each dimension in the dimensions array that ssGetBusElementDimensions
returns.
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]; } } }
