自己编写的采用奇异值分解的地震数据去噪研究，内有详细的解释(I have written using singular value decomposition of seismic data denoising, with detailed explanations)

说明：  1、随机生成一个5*5矩阵A，元素符合均匀分布；再随机生成一个5*5矩阵B，元素符合正态分布。对A和B进行加、减、乘、除、比较等矩阵运算，查看运算结果。 2、创建5阶魔术矩阵，求A的行列式、特征值、逆、秩、迹、条件数。 3、假设矩阵 ，求A的LU分解、正交分解、特征值分解、奇异值分解。 4、创建6阶单位稀疏矩阵，并显示其全部元素。 (1, randomly generated a 5* 5 matrix A, elements in line with uniform distribution then randomly generated a 5* 5 matrix B, elements in line with normal distribution. Pairs of A and B to add, subtract, multiply, divide, comparison matrix operations, view the results of operations. 2, create a 5-order magic matrix, find A, determinant, eigenvalues, inverse, rank, trace, the condition number. 3, assuming that matrix, find A, LU decomposition, orthogonal decomposition, eigenvalue decomposition, singular value decomposition. 4, create a six-order unit of sparse matrix, and display all of its elements.)

可生成从任意点发射攻击全球任意点的一条最小能量弹道，并确定关机点参数。(Can generate a minimum energy trajectory launch attacks from any point to any point worldwide, and to determine the shutdown point parameters.)

This document shows in a simple way the near field of a dipole.You can choose the length of it.furthermore if anyone ask about this problem,please send a comment.

说明：  差分进化程序，有注释，可以直接修改函数运行！(Differential evolutionary process, there are notes, you can directly modify the function to run!)

这是一个基于关于伺服系统的滑模控制的仿真程序，伺服系统为基于S的数学模型，对于研究滑模控制会有帮助(sliding mode control of the sevo system)

使用MATLAB函数中的FFT命令计算离散时间信号的频谱，以加深对离散信号的DFT的理解及其FFT算法的运用。(using MATLAB function FFT calculation order discrete-time signal spectrum, to increase the discrete signals in the DFT and FFT algorithm understanding of the application.)

Inharmonic tone generation

说明：  该程序用来检验monte carlo随机数的分布是否满足随机性要求。包括独立性检验、均匀性检验和参数检验。(procedures used to test the Monte Carlo random number distribution to satisfy the requirements randomness. Including the independence test, uniform test parameters and test.)

对使用高阶累积量（统计量）进行调制识别进行了仿真，包含仿真参考的经典文献和汇报用的PPT。后期我对程序进行了改进，已完美达到文献效果，但PPT中没来得及改，请注意。有极强参考价值(Order cumulants (statistics) modulation recognition simulation contains the simulation reference classic literature and reporting with PPT. The late I program improvement, has the perfect reach literature effect, but did not have time to change, PPT Please note. Have a strong reference value)
