It includes\ncomplex, real, and parallel transforms, and can handle arbitrary\narray sizes efficiently.  FFTW is typically faster than other\npublicly-available FFT implementations, and is even competitive\nwith vendor-tuned libraries.  (See our web page for extensive\nbenchmarks.) To achieve this performance, FFTW uses novel code-generation\nand runtime self-optimization techniques (along with many other\ntricks).\n","package_architecture":"amd64","stem":"fftw","readme":null,"dependencies":[],"reverse_dependencies":{"count":2,"url":"/packages/data/58/586ff10b7af3c80716db5028a63b183a466a1f52350b96b5217b55e7ded9f5d1.json"},"categories":["math"],"flavors":[],"only_for_architectures":[],"not_for_architectures":[]}}
