信号瞬时频率的MATLAB实现计算，用于信号的分析(MATLAB realization of the signal instantaneous frequency calculation for signal analysis)

说明：  解非线性方程快速PSO方法解非线性方程快速PSO方法解非线性方程快速PSO方法(PSO filter good PSO filter good PSO filter good PSO filter good PSO filter good PSO filter good )

说明：  最小均方自适应滤波器（LMS）是由Widrow和Hoff在1960年始创，它是以横向（即抽头延时线）结构为基础构建的。其最基本的形式设计简单，性能也高度高效。这两个特性使得LMS滤波器在各种应用中非常流行。递归最小二乘自适应滤波器（RLS）由于可提供快收敛速率而且对输入信号相关矩阵特征值扩散度变化不敏感，从而突破了LMS族的某些实际限制；其代价是增加了计算的复杂度。(the LMS algorithm of adaptive filter)

说明：  通带截止频率 =1000Hz，阻带截止频率 =1200Hz，采样频率fs=5000Hz，通带衰减系数 =0.3dB，阻带衰减系数 =40dB。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter. )

内弹道计算程序，准确描述了内弹道过程，通俗易懂(Interior ballistics calculation program, an accurate description of the interior ballistics process, straightaway)

NEWTON RAPSHON METHOD FOR LOAD FLOW

This demo tracks cars in a video by detecting motion using optical flow. The cars are segmented from the background by thresholding the motion vector magnitudes. Then, blob analysis is used to identify the cars.

数控车床刀件运动点从TXT文件提取至EXCEL。TXT文件中对车床刀件运动位置描述同时包括字符和数字，程序运行后将提取数据至excel(CNC lathe data processing by matlab(pick up data from txt file and store it in excel))

在PDSCH信道下，运用非正交的知识做的系统级仿真，并采用编码译码方式降低用户的误码率。(In PDSCH channel, the use of non-orthogonal knowledge to do system-level simulation, and the use of codec way to reduce user error rate.)
