事件检测代码，比较简单，仅供参考

基于matlab 的动力学工具箱 做多体或机器人方向的可以看看(SPACELIB is a software library useful for the realization of programs for the kinematic and dynamic analysis of systems of rigid bodies. This library is currently used in ROBOTICS and BIOMECHANICS. It has been developed at the Mechanical Engineering Department of the University of Brescia)

信号、系统及频率响应，离散时间傅立叶正反变换，离散LTI系统的频率响应(Signals, systems and frequency response, both positive and negative discrete-time Fourier transform, discrete frequency response of LTI system)

矩阵功能的演示 首先显示矩阵 所有数据按照MATLAB中的矩阵操作实例实现(Matrix function shows the first display all the data matrix in the matrix operation in accordance with examples of MATLAB Implementation)

实现算术编码的MATLAB仿真研究，得到算术码！(Implementation of the MATLAB simulation of arithmetic coding, arithmetic codes are!)

提出了一种基于小波变换可抗击几何攻击算法。在水印嵌人 部分# 首先对宿主图像进行小波分解 、 嵌人水印, 再通过余弦变换求得该水印图像的一个特征向量, 利用该特征向量和水印 信息通过12 31 函数生成一个二值逻辑系列, 将该序列作为密钥/ 水印提取部分为# 对待测的图像进行小波变换, 再通过余 弦变换求得待测图像的一个特征向量, 利用该特征向量和密钥通过1 2 4 1 函数提取出水印。(Proposed based on wavelet transform algorithm can be against geometric attacks.# Watermark embedded in the first part of the host image wavelet decomposition, embedded watermark, and then through the cosine transform of the watermarked image obtained by a feature vector, using the feature vector and the watermark information through 1231 to generate a binary logic function series, the sequence as the key/watermark extraction part is# treated transform measured image, and then obtained through the cosine transform the image of a feature vector under test, using the feature vector and the key function by 1241 to extract the watermark .)
