Returns a vector containing estimates of the reciprocal square roots of the corresponding elements of the given vector.
d=vec_rsqrte(a)
The following table describes the types of the returned value and the function arguments.
| d | a |
|---|---|
| vector float | vector float |
| vector double | vector double |
Each element of the result contains the estimated value of the reciprocal square root of the corresponding element of a.
