说明：  基于冲激响应不变法巴特沃思滤波器的IIR设计MATLAB源代码(Based on impulse response IIR filter design unchanged 法巴特沃思 MATLAB source code)

用matlab分析由n个单胞组成的桁架在受到最外节点处的集中力是的位移及应力应变，并对整个结构进行优化设计。(Matlab analysis by single cell formed by the n truss subjected to the most outside the nodes in the concentration of power is the displacement, stress and strain, and the entire structure is optimized.)

这是对广义高斯分布中两个参数alpha,beta的估计方法，对自然图像的大量统计特征就符合这一分布。(function [f, g] = dggbeta(beta, absx) DGGBETA Derivative of generalized Gaussian pdf with respective to beta [F, G] = DGGBETA(BETA, ABSX) Return partial derivative and second order partial derivative This is an utility function for GGMLE ABSX is the distance of the data from the mean Function is undefined for negative beta if beta <= 0 f = NaN g = NaN )

本程序的功能是将模型结果直接输出到excel中的演示(The program s function is to generate the result of the model to demonstrate in excel)

说明：  投影寻踪模型，用遗传算法寻求优化投影方向。(Projection Pursuit model using genetic algorithm to optimize the projection direction)

function [mubnd,var,dc,dr,gcr,grc] = bubd(m,blk,Dinitbnd,Ginitbnd,pmu,diagnose,clevel)

program to process steganografi and watermarking

此文件包包含了dijkstra/dynamic.弗洛伊德、克丽丝卡尔、random-generate.binary-search/等算法，是MATLAB路径问题的重要解决方法(This package contains the dijkstra/dynamic. Freud, Kris Carr, random-generate.binary-search/algorithms, MATLAB path problem is an important solution)

说明：  通过粒子群优化算法优化PID参数，该算法对pid控制器参数进行整定，pso能够对参数实现优化，且有良好的收敛性。(PSO algorithm tuning PID parameters)
