利用elta-jerk模型进行卡尔曼目标跟踪，跟踪效果良好(Elta-jerk model by Kalman target tracking, tracking well)

try this for you frieds.....

逆变器的调制方法有多种，如单极性调制，双极性调制，单极倍频调制等，此处是单极性调制，并给出单极性调制发生器(There are many modulation methods for inverters, such as unipolar modulation, bipolar modulation, unipolar frequency modulation, etc. This is unipolar modulation, and a unipolar modulation generator is given)

小波与熵的matlab代码，运行例程，需要的自己改一下(Wavelet and entropy)

基于MUSIC的DOA估计，算法简单较为快捷可以修改(easimation of DOA)

matlab编写的文本分类的程序，可以对已经分好词的文本进行分类，先自己导入数据，用libsvm中的svm进行分类和预测，特征用tfidf算法，还利用卡方检验进行了特征选择，可自行设定阈值。(matlab prepared text classification program, you can have a good word of text classification, classification and prediction using libsvm in svm, characterized by tfidf algorithm, also used the chi-square test was used for feature selection, you can set thresholds on their own.)

说明：  在图像中加入可视水印，用matlab仿真，实验证明保持了较好的图像质量(in adding visual image watermarking using Matlab simulation experiment to prove that maintaining a good image quality)

armold 变换是数字图像置乱中常用的一种方法。本文给出了armold 变换的matlab源代码，以方便大家的使用。(armold digital image scrambling transformation is commonly used methods. In this paper, armold transform matlab source code to facilitate everyone' s use.)
