Effective Interest Method

Problem:Each time a price is displayed on osCommerce the tax rate for that product is queried. Even if the user has set to not display taxes with price the tax rate is queried.Solution:Query for each rate one time as it is needed and then store it in session cache.What this contribution does:This...

Once in a while it becomes necessary to globally change the behaviour of classes in a third party library. This code demonstrates the ability to modify the __init__ method of an arbitrary class in-place. It's also good for making functional programmers wince, which can be entertaining.

The Mann-Kendall Tau-b non-parametric function computes a coefficient representing strength and direction of a trend for equally spaced data. While you do not need the Statistics Toolbox to compute Taub, you do need it to test for significance. This function will compute Tau-b (now tau-a as...

Implements the Complex Method of Constrained Optimization, as proposed by Box (1965), improved by Guin (1968) and Krus (1992), and following the method in Andresson (2001). This is capable of optimizing a "black-box" system with few constraints on the optimization function and requiring no... Platforms: Matlab

A computational method for quantitative analysis by multiwavelength absorption spectroscopy, called the Tfit method, based on fitting a model of the instrumentally-broadened transmission spectrum to the observed transmission data. It has the advantages of wider dynamic range and greatly improved... Platforms: Matlab

this will find the solution of U''=k*U*U' by using taylor series 3rd order and secant methodit gives an idea about the nonlinear ode method and also gives the idea of solving problem in matlab Platforms: Matlab

The conjugate gradient method aims to solve a system of linear equations, Ax=b, where A is symmetric, without calculation of the inverse of A. It only requires a very small amount of membory, hence is particularly suitable for large scale systems.It is faster than other approach such as Gaussian... Platforms: Matlab
