This MATLAB M-file implements a finite-difference time-domain solution of Maxwell s curl equations over a one-dimensional space lattice comprised of uniform grid cells. To illustrate the algorithm, a 1-GHz sinusoidal wave propagating in a nonpermeable lossy medium (epsr=1.0, sigma=5.0e-3 S/m) is modeled. The simplified finite difference system for nonpermeable.

雅可比迭代法，可以解方程数值解。对微分方程的数值解有着重要意义。(Jacobi iteration method, numerical solution of equations can be solved. Numerical solution of differential equations is of great significance.)

说明：  该程序分配时间，用于会面时间的安排，可以用于一周时间的(The program allocation time, the arrangements for the meeting time, the time can be used for a week)

主要是非线性回归程序的源代码，并加载了例子和数据，输出结果是回归模型的模型参数、误差以及假设检验的结果。(Mainly non-linear regression program' s source code, and loads of examples and data, the model output is the regression model parameters, errors, and hypothesis testing results.)

spi总线控制器的程序，实现了同步串行接口的输出(On the spi serial bus interface programming, synchronous transfer)

说明：  matlab 实现的16QAM ,8PSK调制解调以及误码率分析(matlab implementation of 16QAM, 8PSK modulation demodulation and bit error rate analysis)

采用并网电压有效值控制，作为电流内环的给定参考值，单位功率因素运行(use RMS control the voltage and the current)

本代码是PID在S函数中的实现，但不同之处在于，本代码先把PID变成状态空间表达式，更加易懂，为本人独创。(This code is the PID in the S function, but the difference is that, this code to put the PID into the state space expressions, more understandable, for my original.)

用matlab编写的压缩感知DOA,对于超分辨学习很有帮助，内容非常详细(Compressed sensing using matlab DOA, very helpful for super-resolution, very detailed)
