- Finite Volume Poisson Solver
- License: Freeware

C-Library & Matlab Toolbox implement a numerical solution of Poisson equation div(e*grad(u))=f for Cartesian 1D, Cartesian 2D and axis-symmetrical cylindrical coordinates with respect to steeply varying dielectrical permittivity e. Library uses regular rectangular grid with mixed boundary conditions, FVM-based equation discretization and iterative methods for solving sparse linear system. MATLAB VERSION: 6.5 - 7.9 FILES: C-LIBRARY: COMMON.C, COMMON.H - data types, memory management LINALG.C, LINALG.H - solution of tridiagonal system PSN_1D.C, PSN_1D.H - 1D Poisson solver PSN_2D.C, PSN_2D.H - 2D and Cylindrical Poisson solver MATLAB TOOLBOX: PSN_1D_MEX.

- Feature Selection using Matlab
- License: Freeware

The DEMO includes 5 feature selection algorithms: * Sequential Forward Selection (SFS) * Sequential Floating Forward Selection (SFFS) * Sequential Backward Selection (SBS) * Sequential Floating Backward Selection (SFBS) * ReliefF Two CCR estimation methods: * Cross-validation * Resubstitution After selecting the best feature subset, the classifier obtained can be used for classifying any pattern. Figure: Upper panel is the pattern x feature matrix Lower panel left are the features selected Lower panel right is the CCR curve during feature selection steps Right panel is the classification results of some patterns.

- autoassociative memory
- License: Freeware

Develop a Matlab program to demonstrate a neural network autoassociative memory. Show the importance of using the pseudoinverse in reducing cross correlation matrix errors. Show the performance of the autoassociative memory in noise. The results are contained in the Matlab file assoc_mem_demo.m.

- GODLIKE - A robust single-& multi-objective optimizer
- License: Freeware

GODLIKE (Global Optimum Determination by Linking and Interchanging Kindred Evaluators) is a generization of various population-based global optimization schemes. Also, it handles both single- and multi-objective optimization, simply by adding additional objective functions. GODLIKE solves optimization problems using relatively basic implementations of a genetic algorithm, differential evolution, particle swarm optimization and adaptive simulated annealing algorithms. Its power comes from the fact that these different algorithms run simultaneously (linked), and members from each population are occasionally swapped (interchanged) to decrease the chances of convergence to a local minimizer.

- Phase Plot with Time
- License: Freeware

This package contains three files: pptime.m : main file, makes a colored phase plot. Color represents time. pptime_demo.m : demo file, run first in order to see how the program works pend1.m : odefun for damped nonlinear pendulum mode Written and tested in Matlab R14SP2.

- dial
- License: Freeware

Creates a "dial"-style graphical user interface control. Similar in operation and programming interface to Matlab's slider-style uicontrols, but moves in a rotary fashion, rather than linearly. Also different in that a dial control can take minimum and maximum values of -Inf and +Inf. Install by putting "dial" directory on your Matlab path (do NOT add the "dial/@dial/" directory to your path). Run the dial_demo.m program for examples of how to use dial.m. Known bugs: dial objects sometimes very slow to appear and sluggish in response to user inputs. This seems random, and is apparently something internal to Matlab.
