Generalised Logistic Curve

A function which plots the 'Koch curve' fractal.Tested under MATLAB 5.3

The Gini coefficient is a measure of the inequality of a distribution (often used for income or wealth distributions). The Lorentz curve is a graphical representation of this inequality which is intimately related to the Gini coefficient. The program is straightforward to use. Please consult the...

I've seen many people ask for a way to find the closest point on a curve from some given point in space. If the curve is a piecewise linear one, this is not too difficult, since this reduces to finding the closest point on a line segment, and then testing each line segment. (With care, you need...

Generate 'truth tables' where columns correspond to digits in arbitrary mixtures of bases.Normal truth tables enumerate all possible rows of binary digits. In a generalised truth table, the base associated with each digit is arbitrary. This allows exhaustive generation of combinations of...
