Matlab codes for numerical analysis

MSK调制 SIMULINK模块化实现 可以实现误码率的分析(MSK modulation SIMULINK modular BER analysis)

说明：  newton插值应该比lagrange好一点点，适合求解线性方程组，(lagrange interpolation newton than a little bit of good, suitable for solving linear equations,)

雷达成像方面的资深研究专家的博士论文《基于实测数据的雷达成像方法研究》(It is the gradual paper of a professor on SAR/ISAR, which is named SAR_ISAR methods based on pratical datas.)

本程序是切比雪夫低通滤波器，用于电力系统离散数据基波提取(This program is a Chebyshev low-pass filter for extracting the fundamental power system discrete data)

用Simulink实现PAM调制，并显示星座图和眼图(PAM modulation and demodulation)

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)

说明：  求齿轮时变啮合刚度的程序，包含子程序，能跑出图，大家多多下载(The program for calculating the time-varying meshing stiffness of gears, including subroutines, can run out of drawings and download more)

this is very useful file that simulate the memory polynomial method.

此函数包含了IBP算法的matlab源码程序，共享给大家共同学习(This function includes the IBP algorithm matlab source program, to share common learning)
