I\'m seeking a minimal Java wrapper for a recent version of FFTW. The wrappers listed on the FFTW website are either out of date (jfftw-1.2.zip) or contain too much extra stuff
I ended up using JNAerator to automatically generate JNA bindings from the header file fftw3.h. The result is available as a gist on Github. The gist (at the bottom) also includes a convenient Scala interface for real transforms of arbitrary dimension.
