This is a small example code for "Steepest Descent Algorithm". It implements steepest descent Algorithm with optimum step size computation at each step. The code uses a 2x2 correlation matrix and solves the Normal equation for Weiner filter iteratively.Reference:Adaptive Filter Theory 3rd...

Computes BER v EbNo curve for convolutional encoding / soft decision Viterbi decoding scheme assuming BPSK.Brute force Monte Carlo approach is unsatisfactory (takes too long) to find the BER curve.The computation uses a quasi-analytic (QA) technique that relies on the estimation (approximate one)...

Create a random matrix of a non-intercepting snake, like the game ("worm" or "snake"). Also described by filling a chessboard with dominos, except now the board can be rectangular, or any arbitrary shape (by changing the boarders).Uses an infinite loop to enumerate possibilities. There are a...

Two quaternary systems are studied: (1) Acetic Acid - Ethanol - Water- Ethyl Acetate and (2) Acetic Acid - Butanol - Water- Butyl Acetate. In these two systems, liquid phase esterification occurs. The residue curve map is computed using the UNIQUAC model and gas phase acetic acid dimerization....

Two methods are provided -1) an automatic updation method which can be effectively used outside of a loop since it writes out a newton-raphson computation file from the parameters received.2) a manual file generation method; effective when the resulting file has to be called repeatedly in a loop.

This package is the mRMR (minimum-redundancy maximum-relevancy) feature selection method in (Peng et al, 2005 and Ding & Peng, 2005, 2003), whose better performance over the conventional top-ranking method has been demonstrated on a number of data sets in recent publications. This version uses...

The Hodrick Prescott Filter (HP-Filter) is the most popular method to separate a time series x_t into its components. Let's suppose that the original series is composed of a trend component g_t and a cyclical component c_t.Solving the minimization problem is quite simple. This program decomposes...
