bird_egg, a MATLAB code which evaluates some formulas for the shapes of bird eggs.
cosine_transform, a MATLAB code which demonstrates some simple properties of the discrete cosine transform (DCT).
haar_transform, a MATLAB code which computes the Haar transform of 1d or 2d data.
naca, a MATLAB code which takes the parameters of certain NACA airfoils and return the coordinates of a sequence of points that outline the wing shape. The data is displayed graphically.
sftpack, a MATLAB code which implements the slow Fourier transform, intended as a teaching tool and comparison with the Fast Fourier Transform (FFT).
sine_transform, a MATLAB code which demonstrates some simple properties of the discrete sine transform.
walsh_transform, a MATLAB code which implements versions of the Walsh and Haar transforms.
