View official documentation
Purpose:
Duplicates a scalar into every element of the destination vector.
Result:
float16x4_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float16_t value = 1.5f;
float16x4_t result = vdup_n_f16(value);
printf("%f %f %f %f\n", (float)vget_lane_f16(result, 0), (float)vget_lane_f16(result, 1), (float)vget_lane_f16(result, 2), (float)vget_lane_f16(result, 3));
return 0;
