Overview
Computes the sine of the input vector and stores the results in the output vector.
Dispatcher Prototype
void volk_32f_sin_32f(float* bVector, const float* aVector, unsigned int num_points)
Inputs
- aVector: The input vector of floats.
- num_points: The number of data points.
Outputs
- bVector: The output vector.
Example Calculate sin(theta) for several common angles.

float* in = (
float*)

float)*N, alignment);
float* out = (
float*)
volk_malloc(
