A Java translation of fftpack by Baoshe Zhang.
jfftpack is a Java version of fftpack. jfftpack is based on Paul N. Swarztraubre's Fortran code and Pekka Janhuen's C code. It is developed as part of my official duties as lead software engineer for SCUBA-2 FTS projects.
The original fftpack was public domain, so jfftpack is public domain too. This software is in no way certified or guaranteed.
Please send any comments or bug reports to baoshe.zhang at uleth.ca or baoshe_zhang at hotmail.com.
Notes: Please read the documents for FFT formula
if necessary.
