Features

  • The FFT library has been written in Java for portability across different platforms, integrated into a single jar file for easy implementation.
  • The FFT library provides forward and backward fast Fourier transforms in 1-D, 2-D and 3-D with an easy-to-use manner.
  • The FFT requires the length equal to a number with an integer power of two. This library automatically examines the input data and detects the length to prevent improper execution.
