偏微分方程的数值算法，是某高校教授的课程讲义-Partial differential equations of the numerical algorithm, is a University Professor Course Training Manual

利用常用四阶龙格-库塔公式求初值，再利用汉明公式、米尔恩公式和改进的四阶亚当斯隐式公式及常用的四阶龙格-库塔公式求解其余的数值解求解常微分方程初值问题，并计算它与精确解的误差(Use of commonly used fourth order Runge- Kutta initial value to the Formula, and then use the Hamming formula, Milne formula and improved fourth-order implicit Adams formula and the commonly used Runge- Kutta formula for solving the numerical solution for solving the remaining ordinary Differential Equations, and calculate the error it with exact solutions)

This tutorial illustrates the basic ideas of interval type-2 (IT2) fuzzy sets and systems, and provides a Matlab implementation of IT2 fuzzy logic system (FLS). One obstacle in learning IT2 fuzzy logic is its complex notations. In this tutorial we try to avoid these notations and give the reader some intuitive understanding of IT2 FLSs.

说明：  用多层前向网络的BP算法拟合函数 说明：1）网络结构为三层（输入层、1个隐层和输出层）； 2）获取两组数据，一组作为训练集，一组作为测试集； 3）用训练集训练网络； 4）用测试集检验训练结果。(Fitting the function with BP algorithm of multilayer forward network)

说明：  计算阶次分析的案例，需要转速信号进行角度域重采样。(In the case of order analysis, the angle domain resampling of speed signal is needed.)
