Non power of 2 FFT

FFT Performance Benchmarks in .NET

We've had a number of inquires about the CenterSpace FFT benchmarks, so I thought I would code up a few tests and run them on my machine. I've included our FFT performance numbers and the code that generated those numbers so you can try them on your machine. (If you don't have NMath, you'll need to download the eval version). I also did a comparison of 1 dimensional real DFTs, with FFTW, one of...

High Performance FFT in NMath 4.0

The next release of Center Space's NMATH .NET libraries will contain high performance, multi-core aware, fast fourier transform classes. This set of classes will elegantly support all common 1D and 2D FFT computations in a robust easy to use object-oriented interface. The following FFT classes will be available. DoubleComplexForward1DFFT DoubleComplexBackward1DFFT DoubleComplexForw...
