基于matlab的数字图像加密，简单的分层变换(Digital image encryption matlab based, simple hierarchical transformation)

说明：  梯度下降法对数据进行分类，并取了四个数据点，对分类进行证明。对梯度下降法有详细的备注。(The gradient descent method classifies the data and takes four data points to prove the classification. There are detailed remarks on gradient descent method.)

采用脉冲响应不变法和双线性变换法设计IIR数字滤波器。 (Using impulse response method and bilinear transform IIR digital filter design. )

Using Over complete subband

程序功能：大方位失准角初始对准（摇摆基座初始对准）(Procedure function:The generous loses accuracy Cape beginning to start to aim at(sway a base beginning to start to aim at))

说明：  本文件主要是针对于粒子群算法在matlab环境中地应用说编写地m文件！其中粒子群算法地目标函数可在源程序中自行更改！ -(this document is mainly targeted at PSO algorithm in Matlab environment application to the preparation of that document m! )

一个自己用到的用matlab编写的fdtd源程序，感觉还可以。里面的参数没有设置，可以自己根据需要设置。(Used with its own written fdtd matlab source, feeling okay. Inside the parameter is not set up my own according to their needs.)

matlab写的蛇形算法，效果很好，内附图片，通过改变输入的图像运行自己的程序。( snake algorithm with matlab , works well.)

basic dsge model in dynare

说明：  对于一个时间序列，通过奇异谱分析，实现去噪和平滑(realizing SSA for time series)
