大连理工大学矩阵与数值分析上机作业

有限元求解柏松方程。本文采用FORTRAN语言编制程序。程序中大部分变量采用有名公共区存储方式存储，这样可以减少内存占用量。 IFG：生成有限元网格信息，即元素节点局部编码与总体编码对照表，节点实际坐标，边界节点编码与边界点上的已知值 GKD：生成总刚一维存储对角元的地址，计算总刚一维存储长度 FIXP：设置已知节点函数值 GK(NI,NJ,ADJ,AIJ)：单元刚度矩阵计算 GF(NI,N,M,LE,YI,FE)：单元列阵的计算 AK(I,J,AIJ)：总刚度矩阵元素迭加 QEB：总刚度矩阵和总列阵合成 BDE：边界条件处理 SOLGS：Gauss-Seidel迭代法求解方程组 UDIFF(NI,NFLAG,UDIF,LE,ADJ)：标准元素内形状函数导数计算 DIFF：节点上 ， 加权平均 (In this program, FEM was used to solve the possion equation. It is implemented through FORTRAN)

数值模拟方腔内Rayleigh-Benard对流。采用交错网格投影法，能量方程采用松耦合方法。(Numerical Simulation of square cavity Rayleigh-Benard convection. Using staggered grid projection method, the energy equation using loosely coupled approach.)

三种帧同步算法的MATLAB代码,具有良好的算法效果，可以使用，请大家下载(Three kinds of frame synchronization algorithm MATLAB code, a good algorithm results, you can use, please download)

一个简单的计算块的运动矢量源码，使用四步搜索算法(A simple calculation of the block motion vector source, use the four-step search algorithm)

这个程序用来计算四阶累计量，程序中有详细说明(This procedure used to calculate the fourth-order cumulant, the program in detail)

说明：  卡尔曼初始对准主程序，说明了卡尔曼滤波在初始对准里的应用(Main program of Kalman initial alignment)

说明：  berkeley加州大学SAP系列软件之SolidSAP，由Edward L.Wilson教授开发的三维结构源程序，功能强大，代码清晰，含学习手册。(SolidSAP, a three-dimensional structure source program developed by Professor Edward L. Wilson, is a software of the SAP series at the University of California, Berkeley. It has powerful functions, clear code and learning manual.)

有均匀线阵的CRB曲线，自己编的5种调制信号，用于建立主成分分析模型。( There ULA CRB curve, Own five modulation signal, Principal component analysis model for establishing.)

基于模糊控制的MATLAB避障算法，课设内容，最后效果还不错。(Based on the fuzzy control of MATLAB obstacle avoidance algorithm, teaching content, the final effect is not bad.)

This FDTD 2D simulation based on Dennis Sullivan book s. Wave propagation in vacuum background using PML boundary conditions.
