Overview
This block computes the dot product (or inner product) between two vectors, the input
and taps
vectors. Given a set of num_points
taps, the result is the sum of products between the two vectors. The result is a single value stored in the result
address and will be complex.
Dispatcher Prototype
void volk_32fc_32f_dot_prod_32fc(
lv_32fc_t* result,
const lv_32fc_t* input,
const float * taps,
unsigned int num_points)
Inputs
- input: vector of complex samples
- taps: floating point taps
- num_points: number of samples in both
input
and taps
Outputs
- result: pointer to a complex value to hold the dot product result.
Example
int N = 10000;
<populate x and t with some values>
volk_32fc_dot_prod_32fc(&y, x, t, N);
