Chapter 10. Fourier Transforms, Convolution and Correlation (.NET, C#, CSharp, VB, Visual Basic, F#)
NMath provides classes for performing Fast Fourier Transforms (FFTs) on real and complex 1D and 2D data, and for performing linear convolution and correlation on real and complex 1D data. This chapter describes how to use the FFT, convolution, and correlation classes.
