fdtd-codes

使用PML吸收边界三维FDTD算法MATLAB代码(PML absorbing boundary using three-dimensional FDTD algorithm MATLAB code)

本例用五点差分法求解一个二阶偏微分方程，其间用Gauss-Seidel迭代求解(This example uses a five-point difference method for solving second order partial differential equations, during use Gauss-Seidel iterative)

EMD程序用于分解非线性非稳定性的曲线，对数据进行分解成本征模态函数，(The empirical mode decomposition and the Hilbert spectrum for nonlinear and non-stationary time series analysis)

to find a losses in tranmission line

经验模态分解代码，依据数据自身的时间尺度特征来进行信号分解，无须预先设定任何基函数。(Empirical mode decomposition code, based on the data of their characteristic time scale for signal decomposition, no need of any of a set of basis function.)

maximum likelihood fitting for MATLAB .m file

实现加权最小二乘拟合，经典的系统辨识方法，很管用(Achieve a weighted least-squares fitting, classical system identification methods, it is useful)

该程序为盲源分离的仿真程序，对卷积模型的混合图像信号进行分离(The program for the blind source separation of the simulation program, a mixed model of convolution image signal separation)
