用Matlab编写可一个可看的时钟模拟器，指针形式不是数值形式。(Using Matlab to write a simulator to see the clock, not the form of a pointer value in the form.)

PQ分解求解 N节点网络的潮流 可以自行修改 提高收敛速度 (PQ decomposition to solve N node network trend can modify to improve the convergence speed)

基于零阶近似法的稳定性叶瓣图的matlab编程(Based on the zero-order approximation of the stability lobe diagram matlab programming)

呵呵,第一次来很多东西不懂 还请多多指教啊! 几个编的简单的FFT和滤波器设计 希望能有点用(Oh, the first to understand a lot of things you will also enlighten ah! several series of simple and FFT filter design with a little hope)

本程序是龙哥库塔方程及volterra级数的结合，目的是寻找最优解来求出volterra级数核的运算，该算法经过验证，具有可行性(This program is a combination of Long Ge Kuta equation and volterra series, the aim is to find the optimal solution to obtain nuclear volterra series of operations, the algorithm is proven, feasible)

zernike矩的matlab程序，Zernike 矩是一组正交矩,具有旋转不变性的特性。 (matlab program zernike moments, Zernike moments is a set of orthogonal moments, with rotation invariance properties.)

有限反馈的仿真程序，当反馈比特数不同时候的系统吞吐量的变化。(Limited feedback simulation program, when the feedback bit different when the system throughput changes.)

三项锁相环：利用park变换和clark变换，将三相电网电压，变换为两相旋转坐标系下的电压。同时跟踪A相电压的相位角(Three phase-locked loop: the use of park conversion and clark transformation, the three-phase voltage, transformed into two-phase rotating coordinate system voltage. While tracking the phase angle of phase A voltage)

这个是一个倒立摆的控制设计程序，用 c写的可执行文件(This is an inverted pendulum control design procedure)
