Variable Cost Theory

The three-variable autocatalator is a prototype of complex dynamical behavior. Indeed, period doubling and chaos are found when the bifurcation parameter, nu, is varied between 0.10 and 0.20.The autocatalator's steps are the following:P->AP+C->A+CA->BA+2 B->3 BB->CC->DWhere P is a chemical...

Tools for computing amortization schedules with variable interest rates are quite uncommon as opposed to those for computing their fixed interest-rate counterpart.This code (hopefully) helps filling the gap. It is an .m file functionally written as: [Amorout,T,Ratio] =... Platforms: Matlab

This code implements two variations of the paper"High accuracy optic flow using a theory for warping" presented at ECCV 2004 by Dr. Thomas Brox.Its variants appeared in "Particle Video"presented at CVPR 2006 by Dr. Peter Sand.The files optical_flow_brox.m andoptical_flow_sand.m are the files you...

The script solves the problem of assigning a variable name that changes with each iteration, while saving the result using a for loop.It uses a multidimensional array as input and produces matrices as outputs (ASCII). Platforms: Matlab

XI = findX(X,Y,YI) estimates the XI values at which the dependentvariables Y reach or cross a specified target level YI (scalar value). If there are multiple solutions, findX finds all of them. It may be seen as the "inverse" operation of the MATLAB's functionINTERP1, under 'linear' method.X is a... Platforms: Matlab

The response variable is discrete ( it could be binary or multinomial), it could have "k" groups (k=2 binary, k>2 multinomial). the categorical can have "c" categories. The routine finds the weights for each category using the Fisher's method described inHubert J. Carl, Wisenbaker M. Joseph,... Platforms: Matlab

This function generates a vector of triangular distributed continuous random variable. By specifying minimum value(a), maximum value(b), mode(c), and number of variables to be generated(n), the function gives a vector of random variables as output (X). The command syntax is X=trirnd(a,c,b,n).You... Platforms: Matlab

This GUI demo shows how a random variable, X, is transformed to a new random variable, Z, by a function z=f(x). The random variable X can have a uniform probability density function (pdf), a Gaussian pdf, or ?Other pdf? given by a user specified MATLAB expression. A pseudo-random number generator...

This function generates random Bernoulli variables. There is often a need to generated a random variable that has Bernoulli distribution. This function generates Bernoulli random variables 0 and 1. Platforms: Matlab

I needed a way to visualize a subset of a 2D variable derived from a 2D dataset, _together_ with the original data and in its original coordinates. Since a plain 3D plot decouples all this info (and becomes illegible for data containing very noisy regions) I decided to show the calculated 2D... Platforms: Matlab

It finds a (near) optimal solution to a variation of the M-TSP (that has a variable number of salesmen) by setting up a GA to search for the shortest route (least distance needed for the salesmen to travel to each city exactly once and return to their starting locations).Each salesman travels to...
