Java 16 SIMD support for faster lib #2

Hi , Java 16 has released Vector API

You can look at the links for details: https://metebalci.com/blog/what-is-new-in-java-16/ https://openjdk.java.net/jeps/338

Java 16's SIMD API has intrinsic capability. Much faster then JNI.That directly converts these method calls to ARM NEON or AVX512 etc..

It will be good to fit fourier-transform-library to new Java 16's Vector API

Hello sorry for the delay. It would be fun to use this Java Vector API, I'll try to work something with it in the next weeks

So after having a look at the API and re-read the Fourier formula, I have to say my math skills are a little rusty. I wouldn't even know how to represent a complex number in FloatVectors or DoubleVectors

If you have any leads for me, please feel free to share them
