Program for Sellmeier equation of pure glass @20°C in the bandwidth 0.2-1.7 um. In the program n is the obtained refractivr index whereas l is the wavelength.

An application for recognising diffrent shapes in matlab

说明：  这是一个基于GUI系统。该软件已经过测试，并基于MATLAB版本6.0与信号处理和通信工具箱选项以上。(This is a GUI-based system. The software has been tested and based on MATLAB version 6.0 with signal processing and communication over the toolbox option.)

包含各种自适应滤波程序，线性、非线性，FIR及IIR,matlab实现(Program includes a variety of adaptive filtering, linear, nonlinear, FIR and IIR, matlab implementation)

介绍一个稳健性分析工具箱。主要做稳健性主成分、主成分回归、分类。(Our toolbox currently contains implementations of robust methods for location and scale estimation, covariance estimation (FAST-MCD), regression (FAST-LTS, MCD-regression), principal component analysis (RAPCA, ROBPCA), principal component regression (RPCR), partial least squares (RSIMPLS) and classification (RDA). Only a few of these methods will be highlighted in this paper. The toolbox also provides many graphical tools to detect and classify the outliers. The use of these features will be explained and demonstrated through the analysis of some real data sets.)

计算一维和二维表面粗糙度Ra，根据需要自行选择。(Calculate one and two dimensional surface roughness Ra, according to the needs of your choice.)
