View official documentation
Purpose:
Extracts a single element from a vector at the specified lane position. The lane index must be an immediate value within the valid range for the vector size.
Result:
float64_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float64x2_t v = {
1.0, 2.0
};
float64_t result = vgetq_lane_f64(v, 1);
printf("%f\n", result);
return 0;
}Prototypes
Assembly Instruction:
DUP
Usage:
float64_t result =
vgetq_lane_f64(
float64x2_t a, const_int b
)
