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];
        }
     }
  }
