Overview

Multiplies two input floating point vectors together.

c[i] = a[i] * b[i]

Dispatcher Prototype

void volk_32f_x2_multiply_32f(float* cVector, const float* aVector, const float*
bVector, unsigned int num_points) 

Inputs

• aVector: First input vector.
• bVector: Second input vector.
• num_points: The number of values in both input vectors.

Outputs

• cVector: The output vector.

Example Multiply elements of an increasing vector by those of a decreasing vector.

int N = 10;
unsigned int alignment = volk_get_alignment();
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_multiply_32f(out, increasing, decreasing, N);
 
for(unsigned int ii = 0; ii < N; ++ii){
    printf("out[%u] = %1.2f\n", ii, out[ii]);
}
 
volk_free(increasing);
volk_free(decreasing);
volk_free(out);
