joukowsky_transform is available in a Python version.
bird_egg, a Python code which evaluates some formulas for the shapes of bird eggs.
cosine_transform, a Python code which demonstrates some simple properties of the discrete cosine transform (DCT).
haar_transform, a Python code which computes the Haar transform of 1d or 2d data.
naca, a Python 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.
polyomino_transform, a Python code which applies reflection and rotation transforms to the matrix that represents a polyomino.
sftpack, a Python code which implements the slow Fourier transform, intended as a teaching tool and comparison with the Fast Fourier Transform (FFT).
sine_transform, a Python code which demonstrates some simple properties of the discrete sine transform.
