Overview

Accumulates the values in the input buffer.

Dispatcher Prototype

void volk_32fc_accumulator_s32fc(lv_32fc_t* result, const lv_32fc_t* inputBuffer,
unsigned int num_points) 

Inputs

• inputBuffer: The buffer of data to be accumulated
• num_points: The number of data points.

Outputs

• result: The accumulated result.

Example Calculate the sum of numbers 0 through 99

  int N = 100;
  unsigned int alignment = volk_get_alignment();
  lv_32fc_t* vec = (lv_32fc_t*) volk_malloc(sizeof(lv_32fc_t)*N, alignment);
  lv_32fc_t* out = (lv_32fc_t*) volk_malloc(sizeof(lv_32fc_t), alignment);
 
  for(unsigned int ii = 0; ii < N; ++ii){
      vec[ii] = lv_cmake( (float) ii, (float) -ii );
  }
 
  volk_32fc_accumulator_s32fc(out, vec, N);
 
  printf("sum(0..99)+1j*sum(0..-99) = %1.2f %1.2f \n", lv_creal(*out) , lv_cimag(*out)
);
 
  volk_free(vec);
  volk_free(out);
