Overview

Multiplies a floating point vector by a floating point scalar.

Dispatcher Prototype

void volk_32f_s32f_multiply_32f(float* cVector, const float* aVector, const float
scalar, unsigned int num_points) 

Inputs

• aVector: The input vector of floats.
• scalar: the scalar value to multiply against aVector.
• num_points: The number of data points.

Outputs

• cVector: The output vector of floats.

Example

int N = 10;
 unsigned int alignment = volk_get_alignment();
 float* increasing = (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] = 2.f * ((float)ii / (float)N) - 1.f;
 }
 
 // Normalize by the smallest delta (0.2 in this example)
 float scale = 5.0f;
 
 volk_32f_s32f_multiply_32f(out, increasing, scale, N);
 
 for(unsigned int ii = 0; ii < N; ++ii){
     printf("out[%u] = %f\n", ii, out[ii]);
 }
 
 volk_free(increasing);
 volk_free(out);
