高阶谱估计被开发出来，一直为人们所关注，只要信号和噪声中有一种是高斯分布，则累量的运用非常方便解决问题！(Higher order spectral estimation have been developed, has been a continuing concern, as long as there is a signal and the noise is Gaussian distribution, the cumulative amount of use is very easy to solve the problem!)

研制了一套基于pulse多分析仪的声级计自动检定测试系统，主要介绍了系统的工作原理，实现方法及应用(the automatic measurement system of sound level meter is carried out,this system is built on the pulse multi-analyzer)

说明：  功率放大器无记忆模型saleh的MATLAB程序(Memoryless Saleh model power amplifier of the MATLAB program)

利用Rossler吸引子，求五阶全互连细胞神经网络系统的李雅普诺夫指数，判断该系统是超混沌系统(Lyapunov exponents pedigree chart)

本程序实现了一维稳态无源项的对流-扩散方程的数值解法，采用的离散格式包括中心差分，一阶迎风，混合格式与QUICK格式。并画出其与精确解的比较。(This program implements a one-dimensional steady-state convection passive items- diffusion equations numerical solution, a discrete format used include center differential, the first order upwind, mixed format QUICK format. And draw the comparison with the exact solution.)

一个基于矢量控制的无速度传感器MATLAB仿真模型。(Based on vector control without a speed sensor MATLAB simulation model.)

A very simple Gaussian elimination code in matlab

直方图相关内容，有兴趣的人可以看一下，用matlab编写的m文件(Histogram content, those who are interested can look at using matlab m file)

详细介绍了永磁同步电机的控制策略和控制算法。采用的是自抗扰控制算法。(The control strategy and control algorithm of permanent magnet synchronous motor (PMSM) are introduced in detail. The auto disturbance rejection control algorithm is used.)

利用matlab实现功率谱估计中的间接法，不是通过函数调用实现的，是根据算法的思想，一步一步实现的，文件夹中还有实现自相关的算法(Using matlab to achieve the indirect method of power spectrum estimation, not by function calls, is based on the idea of ​ ​ the algorithm, step by step, the folder also auto-correlation algorithm)
