code-Feature-Selection-using-Matlab

The goal of this program is to demonstrate the construction of a huffman encoding tree. The tree is represented as a binary tree using MATLAB s built in treeplot commands. Contruction of the tree as well as the huffman code book will be described in later sections.

单神经元PID解耦控制程序,解耦算法例子以活套系统为传递函数。(Single Neural Net PID Decouple Controller based on Hebb Learning )

MATLAB实现主成分分析，主成分分析可以用于预测，评估等，应用范围广泛(MATLAB realization of principal component analysis)

说明：  利用双边滤波器实现图像的去噪处理，BF是一种有效的边缘保持滤波器，可以获得较好的去噪效果。(The image denoising is realized by using bilateral filter. BF is an effective edge preserving filter, which can obtain better denoising effect.)

程序展示了使用EM algorithm来训练GMM(Gaussian Mixture Model)来进行binary classification。(Program demonstrates the use of EM algorithm to train the GMM (Gaussian Mixture Model) for binary classification.)

各种雷达信号的生成程序，包括二相编码、四相编码、LFM信号等(Various radar signal generator, including two-phase coding, four-phase coding, LFM signals)

小波包分解的MATLAB代码，代码有详细的注释，容易看懂(MATLAB code for wavelet package decomposition)

其实popupwindow用起来比Dialog 方便，因为dialog一切都需要你自己来实现，而popupwindow帮我们实现了很多，我认为在使用的时候关键我们要看清参数： popupWindow.showAtLocation(parent, gravity, x, y) parent这个是一个父view试图， gravity 这个默认是居中，我们要指定显示方式：Gravity.LEFT | Gravity.TOP 最后两个参数就是显示的坐标位置，这样就可以根据需求自己定位显示位置了
