kaerman 滤波MATLAB工具 以及程序(kaerman MATLAB TOOL)

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)

根据物理学的毕奥-萨法尔定理，计算环形线圈周围电磁场的强度。。(According to physics, Biot- Safar theorem, calculate the intensity of electromagnetic field around the circular coil. .)

二维对流扩散问题的各种求解方法结果的比较，采用有限体积法(Two-dimensional unsteady heat diffusion and convection equation and finite volume fortran program)

市场最优配置，通过拉格朗日算子进行计算，并派出最优方案 (Market, the optimal configuration, through the Lagrangian operator is calculated, and to send the optimal program)

说明：  用卡尔曼滤波方法对圆周运动进行预测的算法实现(Kalman filtering method using circular motion algorithm to predict)
