基于matlab的彩色图像转成灰度图像，然后进行图像旋转并画布扩大，最后进行均值插值(Matlab-based color image into gray image, and then expand the image rotation and canvas, and finally to mean interpolation)

基于瞬时频率的码元速率估计，mpsk函数和test_signal函数都在基于小波变换压缩包内(Symbol rate estimation based on instantaneous frequency, qpsk function and test_signal functions in the compression package based on wavelet transform)

非线性方程组的一般解法，matlab用~(FXZXEC( Property , Value ,...) creates a new FXZXEC or raises the existing singleton.Starting from the left, property value pairs are applied to the GUI before fxzxec_OpeningFunction gets called. An unrecognized property name or invalid value makes property application stop. All inputs are passed to fxzxec_OpeningFcn via varargin.)

远程监控系统，具体不知道 ，刚接触，好多不懂，所以才来找学习的软件(Remote monitoring system, specifically do not know, are new, many do not understand is why they come to learn the software)

了等距线阵方向图与傅立叶变换的一致性，用F丌算法进行阵列方向图快速计算。通过严格的数学推导，揭示变换序列与可见空问的关系，讨论了不同单元问距情况下的处理方法(In this paper，the consistence of equispaced linear array pattem and foureir transfom is analyzed，so the linear arrayy pattem can be computed rapidly with FFT a1goritllm．By the use of reUgious mathmatic deducing process，relation between transfotmation sequences and visible space are given，and different handling procedures are discussed in the case of different element spacing． )

Animation shows particle motion along the helix. Main file is MotionOnHelix.m This is example how Matlab can be used for educational purposes, for teaching multivariate calculus.

EM算法，是一种无监督的聚类算法，可以实现对数据的处理，对不同数据进行聚类，生成类内相似度最大(EM algorithm is an unsupervised clustering algorithm, the data processing can be achieved on different data clustering, to generate the maximum within-class similarity)
