说明：  该程序包含低通、高通滤波功能的轮次平稳性检验法(The program includes low pass, high pass filter function in a smooth round test method)

关于滤波的程序，可以减少Gipps效应，提高信号的分辨率。(On filtering procedures, can reduce the Gipps effect, improve the resolution of the signal.)

一个二维静电场，电位函数为φ（x, y），将正方形分成25个正方形网格。有16个内部网格点。假定16个网格点的初值都定为零，试用超松弛法确定16个内部网格点的电位值。(A two dimensional electrostatic field, the potential function for phi (x, y), the square into 25 square grid. There are 16 internal grid point. Assume that 16 mesh point of initial value at zero, trial overrelaxation method to determine the potential value of 16 internal grid point.)

如何用Matlab画图 以西东方向为横轴，以南北方向为纵轴。（选适当的点为原点）将国土最西到最东边界在x轴上的区间划取足够多的分点xi，在每个分点处可测出南北边界点的对应坐标y1 ，y2，(How to use Matlab drawing XiDong direction in the north and south direction for the horizontal axis, for the vertical axis. (choose appropriate point for starting point the west to the east land border on the x axis of interval strokes on the locations take enough in every cent point place xi, can detect the north-south border points corresponding coordinates, y2 y1, )

有关有限元的基本理论与matlab的编程，是浙大徐荣桥老师编写的研究生教材。(For the basic theory and finite element matlab programming, Xu Rong bridge is Zhejiang University graduate teacher preparation materials.)

fastICA,进行串行盲源分离的一种不错的方法(fastICA, serial blind source separation method for a good)

kalman 演示程序 是kalman 滤波器MATLAB仿真(kalman filter smulation )

用一阶梯度法，共轭梯度法和变尺度法求解多变量的寻优问题，其中单变量的寻优用的是0。618法(One method used ladder, conjugate gradient method and the variable metric method for solving multi-variable optimization problems, single-variable optimization using the 0.618 Act)

说明：  移相全桥变换器的建模与仿真，希望对电力电子的同学有用。(The whole bridge converter phase shifting of the modeling and simulation, the hope of power electronic classmates useful.)

波音747仿真实例，里面包含波音747的部分数据以及仿真结果等等相关内容。(747 simulation example, which contains the 747 part of the data and simulation results.)
