QUADCC is a robust, doubly-adaptive quadrature routine using Clenshaw-Curtis rules.This is a Matlab implementation of "Algorithm 3" as described in "Increasing the Reliability of Adaptive Quadrature Using Explicit Interpolants", P. Gonnet, ACM Transactions on Mathematical Software, 37 (3), art.... Platforms: Matlab

This technique simply calculates variation based on a comparison of all abundances in a time series, and is free of assumptions of an underlying 'normal' distribution. It is more robust that the coefficient of variation CV and/or the standard deviation of log transformed abundances SDL, it is not... Platforms: Matlab

Graphical Black and Shcoles calculator for visualizing different sensetives of vanila call and put options, stradle and butterfly as a function of underlying price and time to maturityShows the following sensetives:Price of call, put, stradle and butterflyDelta of call, put, stradle and...

X = POWERM_PADE(A,P) computes the P'th power X of the matrix A, for arbitrary real P and A with no nonpositive real eigenvalues, by the Schur-Pade algorithm. [X,NSQ,M] = POWERM_PADE(A, P) returns the number NSQ of matrix square roots computed and the degree M of the Pade approximant used.If A is... Platforms: Matlab

Digital Karma is designed to model & analyze interaction at a fundamental level. It allows researchers to quantify the interactions of any phenomenon, and study the underlying processes graphically. We simulate the evolutionary processes at work behind any system by modeling the interactions... Platforms: Matlab

This m-file deals with the iterated principal factor method (principal axis factoring) thru the R-correlation matrix (without the matrix of data), the latent root criterion, iteration convergence criterion, and uses the varimax factor rotation. It works with an iterative solution for... Platforms: Matlab

arrayadapt provides a convient way to access mxArrays in MATLAB's .mex files.The 'ArrayAdaptor' class template can be specialzed for one of the builtinnumeric types and a fixed number of dimensions. It allows for subscriptedindexing in additon to using C's []-indexing style.An array which is... Platforms: Matlab

This small contribution is useful in cases where you search for the position of a peak within an intensity matrix (correlation or energy fields) of low resolution. Since this is only a 2nd-order-fit the sub-sample accuracy will only be acceptable as long as the peak area is 'smooth' around the... Platforms: Matlab

There are three piles of marbles. You take against the computer. You may take away as many marbles as you want from one pile each turn. Whoever gets the last marble wins. The rules are very simple, but there are many interesting underlying mathematical patterns. See if you can figure these out... Platforms: Matlab
