Features

Single and double precision complex number structs
1D, 2D and 3D complex fast Fourier transform functions
1D real symmetric fast Fourier transform function
Statistical functions for complex data sets (i.e. mean, variance, std. dev., RMS, etc...)
Optimized for speed

Online Documentation

Click here to browse the full contents of the library in MSDN style format. Much thanks goes out to the creators of NDoc -- it was used to generate all the documentation files for this lbrary.

Included Library Demos

Image Filtering Sample

Shows how to convert an image from a spatial representation (i.e. picture on the left) to a frequency representation (picture on the right) using a 2D fast Fourier transform.

Mandelbrot Generator

Just shows how to use the complex number structs to calculate the classic Mandelbrot fractal around zero. Pretty simple but still nice to look at.
