Java Walsh Hadamard transform O'Connor transform

  1. Dec 22, 2009 #1
    I have just created a Java native wrapper for my fast Walsh Hadamard transform and O'Connor Transform code. I am getting 2000 65536-point WHT's per second and 540 65536-point OCT's per second. That is about as fast as you will get without resorting to Nvidia CUDA or whatever.
    The code is here:

    The OCT transforms arbitrary numerical data into data with a Gaussian distribution. It has many uses for compressive sensing, neural nets and genetic algorithms.
    Have fun and be good,
    Sean O'Connor
