How to execute multiple mathematical operations in S-Function using C

I am trying to process the input signal. For this case the S-Function block has two input ports(U and V) and one output port (R). The output is mathematically modeled as R=(U*cos(Omega*i))-(V*sin(Omega*i)). But, while I am trying to implement the operation in S-Function block, the output takes only values of U, and no processing takes place.

The C code for the same is given below:

#define S_FUNCTION_NAME reconstruction
#define S_FUNCTION_LEVEL 2
#include<stdio.h>
#include "simstruc.h"
#include<math.h>
#include<stdlib.h>
//========================================================
// Model Initialization
//========================================================
static void mdlInitializeSizes(SimStruct *S)
{
  ssSetNumSFcnParams(S,0);  // Define the number of input port parameters.

  if(ssGetNumSFcnParams(S)!=ssGetSFcnParamsCount(S))
    return;  // IF THE PARAMETER EXPECTED MISMATCHES WITH ACTUAL PARAMETER THEN RETURN 0;
    if (!ssSetNumInputPorts(S, 2)) return;
  ssSetInputPortWidth(S,0,DYNAMICALLY_SIZED);  // Input port width is dynamically updatable
  ssSetInputPortWidth(S,1,DYNAMICALLY_SIZED);
  ssSetInputPortDirectFeedThrough(S,0,1);
  ssSetInputPortDirectFeedThrough(S,1,1);
  if(!ssSetNumOutputPorts(S,1)) return;  // The output will be the reconstructed signal
  ssSetOutputPortWidth(S,0,DYNAMICALLY_SIZED);
static void mdlInitializeSampleTimes(SimStruct *S)
{
  ssSetSampleTime(S,0,INHERITED_SAMPLE_TIME); // Declares about the inherited Sample Time
  ssSetOffsetTime(S,0,0);
}
static void mdlOutputs(SimStruct *S, int_T tid)
{
  InputRealPtrsType U =ssGetInputPortRealSignalPtrs(S,0); // Imaginary Signal
  InputRealPtrsType V =ssGetInputPortRealSignalPtrs(S,1);  // Real Signal;
  real_T *R= ssGetOutputPortRealSignal(S,0);
  //real_T *I=ssGetOutputPortRealSignal(S,1);
  int_T width = ssGetOutputPortWidth(S,0);
  int_T i;
  real_T Omega=(2*3.1415926535898/8);
  UNUSED_ARG(tid);
  // value of omega is assigned.
  for (i=0; i<width; i++)
  {
    R[i]= ((*U[i]) * cos(Omega*i))-((*V[i]) * sin(Omega*i));
    
  }
}

static void mdlTerminate(SimStruct *S)
{
}
#ifdef MATLAB_MEX_FILE
#include "simulink.c"
#else
#include "cg_sfun.h"
#endif

How to address the problem... Thanks and Regards.
