根据洗衣机振动实验结果，用MATLAB软件进行时域、频率幅值和功率谱分析(According washing machine vibration test results, using MATLAB software for time domain, frequency, amplitude and power spectral analysis)

自适应噪声消除滤波器！是采用的语音信号！欢迎大家下载！(Adaptive noise cancellation filter! Is the use of the voice signal! Welcome to download! )

运用多松弛时间，相对于单松弛，具有更好的稳定性，且数值结果更精确(Compared with single relaxation, multi-relaxation time is more stable and the numerical results are more accurate.)

Voronoi图，又叫泰森多边形或Dirichlet图，它是由一组由连接两邻点直线的垂直平分线组成的连续多边形组成。 N个在平面上有区别的点，按照最邻近原则划分平面；每个点与它的最近邻区域相关联。 Delaunay三角形是由与相邻Voronoi多边形共享一条边的相关点连接而成的三角形。

简单的CMA算法,适合初学者来学习，自己编写的，望采纳。(simple CMA algorithm)

以二体问题为模型，从地球发射航天器探索火星，途中需经过一次无动力金星借力，寻找最优（总速度增量最小）的发射时间窗口和飞行时间，并绘制地球到金星的Pork-Chop发射能量等高线图。发射时间窗口为2023—2033年，总飞行时间不得大于2年。(Taking the two body problem as the model to explore Mars from the earth, it is necessary to seek an unpowered Venus transit force on the way to find the optimal time window and time of flight (the minimum total velocity increment), and draw the contour map of the Pork-Chop emission energy of the earth to Venus. The total launch time window is from 2023 to 2033, and the total flight time is not more than 2 years.)

这是一个音像高低通滤波MATLAB代码，其中包括巴特沃斯低通滤波，高斯高通滤波，高斯低通滤波，理想矩形低通滤波，理想圆形低通滤波……(This is a sound image high and low pass filter MATLAB code, which includes Butterworth low-pass filter, Gaussian high-pass filter, Gaussian low-pass filter, ideal rectangular low-pass filter, ideal circular low-pass filter ...)

This function quickly finds local peaks or valleys (local extrema) in a noisy vector using a user defined magnitude threshold to determine if each peak is significantly larger (or smaller) than the data around it. The problem with the strictly derivative based peak finding algorithms is that if the signal is noisy many spurious peaks are found.

根据m序列的原理，用于产生任意位的小m序列。(According to the principle of m sequences, used to generate random bit sequence of the small m.)
