Computes by using the FFT (fast Fourier transform) algorithm the covolution of two discrete sequences.
This m-function returns the negative hypergeometric probability density function with parameters M, N and A at the values in X. Note: The density function is zero unless M, N and A are integers.
If a lot consists of M acceptable items...

Calculates entropy for data (probability of events) in an array. In information theory, entropy is a measure of the uncertainty associated with a random variable. In this context, the term usually refers to the Shannon entropy,...
Constructs discrete least-squares rational approximations to data using the full-Newton algorithm for solving separable non-linear least-squares problems that was developed in:
Carlos F. Borges, A Full-Newton Approach to Separable...
Discrete-time models: random walk, ARMA, fractional integration, GARCH). Continuous-time counterparts: Levy processes, Ornstein-Uhlenbeck, fractional Brownian motion, stochastic volatility, subordination. To walk through the code and for a...
This collection generates random variables and vectors of random variables with various distributions, including Bernoulli, geometric, exponential, Gaussian, Poisson, discrete uniform, and continuous uniform, based on the parameters you input to...
Design of a robust digital controller with PPR toolbox
This script shows the basic steps for the "digital two degrees of freedom controller" (2DOF) design with the PPR toolbox.
The illustration of our methodology is...
The IEEE Multipath Channel block simulates an indoor UWB channel as described in "A Channel Model for Ultrawideband Indoor Communications" by J.R. Foerster, M. Pendergrass and A.F. Molisch, November 2003, and attempts to incorporate the...
Hidden Login provides easy and discrete access to the admin functionality of your site. Pressing the set keystroke combination will activate Hidden Login, either displaying a modal login window or redirected to the admin area if you are already...
XI = findX(X,Y,YI) estimates the XI values at which the dependent variables 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"...
computes the naturally-ordered discrete Hadamard transform
To enhance the efficiency and accuracy of Kalman filter computations, in particular the time and measurement updates, UDU factorization is employed. An interesting feature of the current implementation is the extension to semi-positive...
Raible's Method Rev.02 This script is used to compute the Raible table for any characteristics polynomial of f(Z) of any order (which saves alot of computing efforts.), accordingly the stability of discrete systems can be easily deduced, also...
This function creates and applies a colormap defined in a color palette table (.cpt) file. Color palette tables are used to define colormaps in the Generic Mapping Tools package (http://gmt.soest.hawaii.edu/). These files provide more flexible...
Wavelet discrete transform based on Haar wavelet serves as a link between wavelet technique of data compression and fractal technique based on the system of contractive linear transforms.
This m-file gives the expansion of powers of sums of any real or complex numbers x and y, and any negative integer n. In 1676 Newton showed that the binomial theorem also holds for negative integers n, which is the so-called negative binomial...
Program given here computes the discrete transfer function of a DC motor (Example taken in this case) using pseudo inverse technique. The input and output data for any single input single output system can be used to find out the discrete transfer...
