A Discrete Fourier Transform (DFT), a Fast Wavelet Transform (FWT), and a Wavelet Packet Transform (WPT) algorithm in 1-D, 2-D, and 3-D using normalized orthogonal (orthonormal) Haar, Coiflet, Daubechie, Legendre and normalized biorthognal wavelets in Java.
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 JWave to new Java 16's Vector API
