The function implement the 1D Walash Transform which can be used in signal processing,pattern recognition and Genetic algorithms. The Formula of 1D Walsh Transform is defined as : N-1 q-1 ---- -- 1 | | b[i](m)*b[q-1-i](u) W(u) = --- / f(m)| | (-1) ,u = 0,...,N-1 N ---- | | m=0 i=0 where for... Platforms: Matlab

% also incorrectly known as Shannon-Weaver,is one of% several diversity indices used to measure versity% in categorical data. It is simply the Information% entropy of the distribution, treating species as% symbols and their relative population sizes as the% probability.% The advantage of this... Platforms: Matlab

This function treats a matrix as a column-wise set of signals and circularly shifts each column so that it aligns with the first column of data so that the inner product between those columns is maximized with respect to all other shifts.

Clipping is the main program. There are three inputs: y is the time record, threshhold_value is the clipping threshhold, and threshhold_samples is the number of consecutive data points exceeding the threshhold_value to indicate that the data is clipped.The program returns two cells arrays...

Most PID tuning rules are based on first-order plus time delay assumption of the plant hence cannot ensure the best control performance. Using mordern optimization techniques, it is possible to tune a PID controller based on the actual transfer function of the plant to optimize the closed-loop... Platforms: Matlab

D = DISTMAT(X,Y) for matrices X and Y returns the distance matrix where the (i,j)th entry is the d-norm distance between the ith and jth row of X and Y respectively.DISTMAT(X,Y,d) computes a specific d-norm distance. Default=2[D,XI,YI]=DISTMAT(X,Y,d,var) gives the indices of the sorted values of... Platforms: Matlab

Where several instruments record a time-series of data with a common time record, quality control and despiking of the data is often linked between the instruments. This function allows a variable number of datasets (with a common time record) to be plotted and scrolled through. Bad data can be... Platforms: Matlab

This is a collection of functions I wrote for use of MATLAB with tree-ring time series. Functions are included for skeleton plotting, group time-series plotting, and correlation analysis of seasonal climatic time series with tree-ring indices ("tree-ring response-functions"). Platforms: Matlab
