Partial-code

针对偏微分方程的MATLAB解法，主要研究微分方程(组)的数值解法（近似解），重点介绍 Euler 折线法．(For the solution of partial differential equations MATLAB, mainly studies the differential equation ( Group ) numerical method ( approximate ), introduced Euler broken line method.)

sinusoidal pulse width modulation (pwm) inverter

最小二乘支持向量回归模型 直接输入训练集和测试样本即可(Least squares support vector regression model direct input training set and test samples )

输入一列整数，选择需要求子列的长度。在求最长子列，(Enter a list of integers, select the Child-giving the length of the column. Having failed to achieve the longest sub-columns,)

说明：  遗传算法的小程序，希望能够对大家有用处！(genetic algorithm for small procedures, we hope to be able to be useful!)

本文是编程来实现图像缩放，从而熟悉图像的几何变换(This is a program to implement image scaling, so familiar with the image of the geometric transformation)

该计算程序可以对无固定约束碰撞振动系统在激励力作用 下的系统响应进行计算，模拟系统动态响应，并自动判断颤振发生情 况，记录不同参数组合（阻尼比，质量比，恢复系数，间隙，频率比） 情况下系统的响应数据，输出发生颤振的参数组合数据。(The program can be used to study the impact force of a vibro impact system with no fixed constraint The system response is calculated, the dynamic response of the system is simulated, and the occurrence of chatter is judged automatically Different parameter combinations (damping ratio, mass ratio, recovery coefficient, clearance, frequency ratio) were recorded In the case of the system response data, the output parameters of flutter data are output.)
