此程序为潮流计算的最后一部分功率计算程序。(This program is the last part of the power flow calculation calculation program.)

该文件解决了电磁场和天线问题计算当中的近远场转换的问题，它也可以应用在一般散射问题的求解中。(this file contains an algorithm that could solve problems within the EM and antenna near to far field questions. Also, it could be used in general scattering problems.)

说明：  使用分布傅立叶法计算非线性薛定谔方程。可以得到光纤非线性传输特性。(Fourier method using the distribution of nonlinear Schr枚dinger equation. Can be non-linear optical transmission characteristics.)

说明：  详细描述了通过卡尔曼滤波算法对GSP和imu数据进行融合(merge the gps and imu with the kalman)

矩阵转换问题 行与列的个数均为n 的矩阵称为n 阶方阵。假定矩阵中的每个元素的值在0到9之间，则可以将矩阵中的所有元素按行依次排列得到一个“单行矩阵字符串”。(Matrix conversion, the number of rows and columns of the matrix n are called n-order square. Assume that each element of matrix value in the 0 to 9, you can press all the elements of the matrix rows in order of priority for a " single matrix string." )

三维矢量有限元-矩量法电磁场分析程序。 EMAP5 is a full-wave electromagnetic field solver that combines the method of moments (MOM) with a vector finite element method (VFEM). It employs the finite element method (FEM) to analyze a dielectric volume, and employs the method of moments (MoM) to solve for currents on the surface of (or external to) this volume. The two methods are coupled through the fields on the dielectric surface.(Three-dimensional vector finite element- MoM electromagnetic field analysis program.
