这是几个pdf格式的集合，主要介绍了simulink的基本操作，对初学者入门有一定帮助(Pdf format This is a collection of several, mainly introduced the basic operation of simulink to help beginners have some portal)

用Matlab编程求解切比雪夫型渐变线的阻抗、线宽和驻波比(Programming with Matlab for solving Chebyshev-type gradient line impedance, line width, and standing-wave ratio)

说明：  matlab 关于牛顿法，最速化，拟牛顿法，黄金分割法，一维搜索法的编程(Matlab of Newton, the most speed, quasi-Newton method, 0.618, one-dimensional search Programming)

1. 608组样本，第一列数字是标号，第二列数字是出现损坏的时间，第三列表示数据有效性，为0有效 2. 损坏时间是对数正态分布的，需要拟合 3. 求均值80%置信区间 4. 成本为m，价格为s，保证盈利20%，选取保修期 5. 比较保修期和拟合数据的均值 6. 若保修期就是拟合损坏时间的均值，求出利润率 loadd.m：加载样本数据，并选取有效数据 period.m：加载成本、价格数据，计算利润和保修期的关系(1.608 groups of samples, the first number is the label, the second column number is the time to appear damage, the third list shows the validity of the data, which is 0 effective. 2. damage times are logarithmic normal distribution and need to be fitted 3. mean in 80% confidence interval 4. the cost is m, the price is s, the profit is 20%, the warranty period is selected. 5. compare the mean value of the warranty period and the fitting data 6. if the warranty period is to fit the mean damage time, the profit rate is calculated. Loadd.m: load the sample data and select the valid data Period.m: loading cost, price data, and calculating the relationship between profit and warranty period)

mathlab code for huffman coding

四节龙格库塔程序，这是一个很高的程序，快来下载吧，齐纳的朋友么(this is a good for everything)

说明：  HFSS在MATALAB中的应用，很好的应用教材(HFSS 3D modeling applications in Matlab)

该程序是MATLAB源程序，可以用来对纹理图像进行分割。(MATLAB source code of the procedure can be used for texture image segmentation.)

说明：  golden code 一种先进的编码方法 性能优越 复杂度低(golden code, an advanced coding method superior performance, low complexity)
