使用matlab打开mdb数据库，并画图(Using matlab to open mdb database, and drawing)

应用matlab应用平台信号采集程序设计与整理。(Application matlab application platform signal acquisition program design and finishing.)

Root Cosine Filter BPSK

以MATLAB將影像做邊緣偵測以及邊緣強化， 邊緣偵測分別為Prewitt以及Canny， 邊緣強化是將邊緣做銳利化(MATLAB will do to the image edge detection and edge enhancement, edge detection, respectively Prewitt and Canny, edge enhancement is done to sharpen the edge)

快速扩展随机生成树算法（RRT）matlab 仿真演示。 (simulation of Rapidly-exploring Random Tree （RRT） based on MATLAB.)

ofdm用bpsk下的编程，最后可以做用ofdm和不用的情况的对比(ofdm bpsk programming)

说明：  Matlab遗传算法工具箱 1.官方文档里面有很多的实例和参数的说明 2.图形化操作之后可以自动生成代码 3.注意在程序里面要关掉打开的文件 fclose(Matlab genetic algorithm toolbox 1. There are many examples and parameter descriptions in the official documents 2. Code can be generated automatically after graphical operation 3. Pay attention to close the open file Fclose in the program)

解决微分方程的matlab程序实现步骤，参考价值高(Matlab program to solve differential equations implementation steps, the reference value is high)

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)
