numerical solutions by devided difference methods

基于分数低阶协方差仿真的时延估计问题，其基本思想是利用两个接收信号的相关函数来估计时间延迟。(Based on the scores of low-level simulation of time delay covariance estimation problem, the basic idea is to use of the two received signal correlation function to estimate the time delay.)

之字扫描，是在JPEG压缩中使用的一个数据扫描格式。自己在MATLAB中编程实现了正反函数。(zigag scanning is a mode of data scanning in JPEG data hoop.This codes realize the zigzag scanning and the inverse zigzag scanning.)

Goal of the project was to use numerical methods for solving systems of ordinary differential equations (ODE) using MATLAB software. As in previous assignments first of all I had to research for algorithms, which would be helpful during evaluation of each task, later on I was able to implement and test numerical methods for solving given problems. Each student received electric circuit containing different elements to solve. Each task is presented under separated heading, with its full description, problem discussion, my approach for solving it and explanation.

power_VariableInductor.rar,功率电子领域matlab仿真文件，已经验证过，程序运行正常(power_VariableInductor.rar,Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

This is the alternating direction method of multipliers by Zouchen Lin

lear N = 10^5 EB_NO = [-1:30] liu1 = zeros(1,N) liu2 = zeros(1,N) for ii = 1:length(EB_NO) m= (2*(rand(1,N)>0.5)-1) + j*(2*(rand(1,N)>0.5)-1) s = (1/sqrt(2))*m normalization of energy to 1 n = 1/sqrt(2)*[randn(1,N) + j*randn(1,N)]

GENETIC ALGORITHM OPTIMIZATION

说明：  这是一个用matlab读取txt（特定格式）文件并读取文件，画出figure，自动保存和关闭figure。程序运用了深度搜索递归算法。（因为大家没有input的txt文件，所以阅读程序领会思想和方法即可）(This is a use matlab to read txt (a specific format) file and read documents, painted figure, on and off automatically to preserve figure. Procedures for the use of recursive depth search algorithm. (Because there are no input of the txt file, so reader can understand the ideas and methods))
