Overview
Adds two vectors together element by element:
c[i] = a[i] + b[i]
Dispatcher Prototype
void volk_32f_x2_add_32f(float* cVector, const float* aVector, const float* bVector,
unsigned int num_points)
Inputs
- aVector: First vector of input points.
- bVector: Second vector of input points.
- num_points: The number of values in both input vector.
Outputs
- cVector: The output vector.
Example
The follow example adds the increasing and decreasing vectors such that the result of every summation pair is 10
int N = 10;
float* increasing = (
float*)
volk_malloc(
sizeof(
float)*N, alignment);
float* decreasing = (
float*)
volk_malloc(
sizeof(
float)*N, alignment);
float* out = (
float*)
volk_malloc(
sizeof(
float)*N, alignment);
for(unsigned int ii = 0; ii < N; ++ii){
increasing[ii] = (float)ii;
decreasing[ii] = 10.f - (float)ii;
}
volk_32f_x2_add_32f(out, increasing, decreasing, N);
for(unsigned int ii = 0; ii < N; ++ii){
printf("out[%u] = %1.2f\n", ii, out[ii]);
}
