C / C ++库FFT与非GPL许可证 [英] c/c++ FFT library with non GPL license
问题描述
我要寻找一个FFT库的许可证允许我把它列入商业C ++软件。免费将是很好。 (英特尔IPPS是每人$ 199,这是developper将编译它的数量有点贵。)
I am looking for a FFT library with a license that allow me to include it in a commercial C++ software. Free would be nice. (Intel IPPS is 199$ per head, which is a bit expensive for the number of developper that will be compiling it.)
任何人有这样的FFT库好的经验?
Anybody has good experience with such a FFT library?
我找到了这个网页,其中列出了很多库:

I found this page, which list a lot of libraries: http://www.fftw.org/benchfft/ffts.html
FFTW是GPL的,所以它不会起作用。任何好的方法吗?
FFTW has a GPL license, so it won't work. Any good alternative?

编辑:有 EigenFFT - 一个C ++ - 前端为KissFFT作为本征的不支持的一部分。
There is EigenFFT - a C++-frontend for KissFFT as an unsupported part of Eigen.
