- Simple example of the Simplex Method
- License: Freeware

It's a function that finds the minimum value of a two variables objective function with a deterministic zero order algorithm: simplex method. The input variables are: -fun: inline function of the objective function -init_point: initial point for the simplex method -step_size: initial dimension of the simplex toll: tolerance for the stop criterion on the simplex dimension -numMaxIter: stop criterion on the maximum number of iterations The output variables are: -valFunc: the minumum value of the objective function -var_min: the minimum point -iter: the number of iteration made %%%%%%%% IMPORTANT %%%%%%%%%%% To run correctly the Matlab function, you must run first a contour plot of the objective function.

- Minimum Entropy Deconvolution (MED 1D and 2D)
- License: Freeware

This is the iterative 2D Minimum Entropy Deconvolution implemented according to an iterative method in the original paper: R.A. Wiggins, Minimum Entropy Deconvolution, Geoexploration, vol. 16, Elsevier Scientific Publishing, Amsterdam, 1978. pp. 21 35. This also works applying the 1D MED when supplied just a single row/column 'x' input. This technique has wide-ranging applications ranging from fault detection to geophysics. It generates a single 1d finite impulse response filter to minimize the entropy of each column filtered by the filter, and is typically applied to extract impulse-like features from signals.

- PERFORMANCE ANALYSIS OF SYMBOL/CHIP BASED MINIMUM
- License: Freeware

Current direct sequence code division multiple access (DS-CDMA) system suffer from Multiple access interference (MAI) and Inter symbol interference (ISI) due to the frequency selective channel. This interference can be avoided by use of Adaptive Beamforming. There are two different minimum variance Beamformer configurations for the base station receiver in direct sequence code division access (DS-CDMA) systems, namely a chip- based and a symbol-based configuration. In this paper chip- based and symbol- based configurations are studied.

- Computation of Stabilizing PI Controllers
- License: Freeware

PITAN(NUM,DEN,W) plots the stability boundary locus L(KP,KI,W) in the (KP,KI)-plane for an LTI system with transfer function defined by its NUM, DEN coefficients and driven by a PI controller with transfer function, C(s)=kp+(ki/s). Frequency (W) gridding become important. The method works for open loop stable or unstable, minimum or nonminimum phase systems. Method and examples used are form "Computation of Stabilizing PI and PID Controllers" by Nusret Tan, Ibrahim Kaya and Dereck P. Atherton..

- Circle Fit (Kasa method)
- License: Freeware

This is the fastest (though not most accurate) method of fitting a circlle to data points on a plane (given by their xy-coordinates). It returns the circle center (a,b) and radius R. It was proposed by I. Kasa in article "A curve fitting procedure and its error analysis", IEEE Trans. Inst. Meas., Vol. 25, pages 8-14, (1976). Another version of this circle fit has been posted by Izhak Bucher (file 5557)..

- Quadratic programming by Wolf's method
- License: Freeware

This script is capable of solving a convex quadratic programming problem by Wolf's method. For the convergence of the algorithm it is necessary that either Hessian of the objective function be positive definite or positive semidefinite Hessian with linear term zero. For theory of Wolf method and QPP one may see "Numerical Optimization with Applications, Chandra S., Jayadeva, Mehra A., Alpha Science Internatinal Ltd, 2009.".

- Pattern search method: deterministic iterative zero order algorithm
- License: Freeware

It's a deterministic iterative zero order algorithm that can be used to solve unconstrained optimization problem. It finds the relative minimum of a two variables function with a deterministic iterative zero order algorithm. Pattern search method It finds the relative minimum of a two variables function with the Pattern search method. The inputs are: - f: matlab inline function of the function that you want minimize; - p0: initial point for the search algorithm - step_size: initial step used for the exploration phase - tolerance: it defines a stopping criterion on the minimum size of exploration phase's step_size - N_it: it defines a stopping criterion on the max iterations number The outpus are: - iter: the number of iterations done - min: the function's value in the relative minimum finded.

- mRMR Feature Selection (using mutual information computation)
- License: Freeware

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 mutual information as a proxy for computing relevance and redundancy among variables (features). Other variations such as using correlation or F-test or distances can be easily implemented within this framework, too.
