title: How to compute the square root of a vector elementwise using vDSP / Accelerate in swift for iOS
body: <p>I have a vector similar to <code>[Float](repeating: 1.0, count: 42000)</code>, and I would like to compute the square root of each element using the Accelerate framework, but no <code>vDSP_vsqrt</code> function exists contrary to what is stated in <a href="https://stackoverflow.com/questions/4251716/apple-accelerate-framework-scale-and-normalize-a-vector">Apple Accelerate Framework scale and normalize a vector</a>. How should I do it?</p>
