View official documentation
Purpose:
Floating-point Square Root (vector). This instruction calculates the square root for each vector element in the source SIMD&FP register, places the result in a vector, and writes the vector to the destination SIMD&FP register.
Result:
float64x1_t
Example:
#include <arm_neon.h>
#include <stdio.h>
int main() {
float64x1_t a = vdup_n_f64(16.0);
float64x1_t result = vsqrt_f64(a);
double res = vget_lane_f64(result, 0);
printf("%lf\n", res);
return 0;

Assembly Instruction:
FSQRT
Usage:
float64x1_t result =
vsqrt_f64(
float64x1_t a
)
