am仿真实现的matlab程序，一共有五个，现分别上传。此程序均为本人及同事呕心沥血所编，现拿来与朋友们分享。(am realize the matlab simulation program, a total of five, are, respectively, upload. This procedure and I are prepared by dedicated colleagues are used to share with friends.)

提出了一种求解电磁场有限元 边界元混合法所生成的线性方程组的有效方法 ———内观 法结合多波前法.由于该线性方程组的系数是一个部分稀疏部分满填充的矩阵,为了加速求解,应用内观法将系数矩阵分为 2块,一块是有限元法形成的稀疏矩阵,另一块是边界元法生成的满阵,然后用多波前法求解稀疏矩阵方程,用高斯 约当消去法解满阵方程. 采用该方法,计算了二维多层介质柱体的雷达散射截面.计算结果表明,该方法的计算效率远远高于传统的高斯法.(Proposed for solving mixed finite element boundary element linear equations generated by an effective method of Vipassana--- a combination of multi wave front method. Since the coefficients of linear equations is a part of the sparsely populated part of the full matrix, in order to speed up the solution, application of Vipassana coefficient matrix is ​ ​ divided into two, one is the finite element method for the formation of the sparse matrix, the other is the boundary element method generates the full array, and then use the multifrontal method for solving sparse matrix equation Gauss Jordan elimination method with full matrix equation solution. use this method to calculate the two-dimensional multi-layer dielectric cylinder of the radar cross section. The results show the computational efficiency of this method is much higher than the traditional Gaussian law.)

计算信噪比，计算公式是信号能量比上噪声能量(SNR Calculation，signal power divide noise power)

用Matlab编写的天空之城，分享给大家听听(Matlab prepared Laputa, share them to you)

对系统进行预测控制，达到提前预防的效果。(To predictive control system, to achieve the effect of prevention in advance.)

飞机飞行仿真中，对四个主要控制量，包括油门、升降舵、副翼及方向舵控制，分别提供持续2秒的随机大小的阶跃控制输入，四个控制量互相独立。可以用于飞行动力学系统辨识、参数识别等。(Flight simulation, the four main control volume, including throttle, elevator, aileron and rudder control, to provide for 2 seconds, respectively, a random step size control inputs, four control variables independent of each other. Can be used in flight dynamics system identification, parameter identification.)

This module will calculate the electrical angle between two different signals (Normally current + Voltage). once the first siganl as a reference signal and once the second signal as a reference signal.

说明：  加权质心定位算法,Matlab程序，应用于无线传感器定位-Weighted centroid location algorithm, Matlab program, used wireless sensor positioning

说明：  在MATLAB的simulink上搭建了电动汽车的同步电机驱动控制电路(The synchronous motor drive control circuit of electric vehicle is built on Simulink of MATLAB)

该程序为GUI学习书籍中的源码以及一些其他的一些关于GUI的例子，程序很多很丰富，希望对学习GUI的同学有参考作用！(The program for the GUI to learn the source books as well as a number of other examples on the GUI, the program a lot of very rich, want to learn GUI-have reference for students!)
