给出一段噪声音乐信号，用滑动平均滤波器进行处理，观察改变滑动窗口宽度对声音效果的影响。 （1）读取一段噪声信号，画出未处理噪声信号的时域波形和信号频谱图； （2）在Matlab中利用滑动平均滤波器对噪声信号进行处理，得出处理后的图像； （3）改变滑动窗口的宽度，观察处理后噪声以及图像得出对效果的影响。(A piece of noise music signal is given. It is processed with a sliding average filter to observe the effect of changing the width of sliding window to the sound effect. (1) a noise signal is read and the time domain waveform and signal spectrum map of the unprocessed noise signal are drawn. (2) in Matlab, a sliding mean filter is used to process the noise signal, and the image after processing is obtained. (3) to change the width of the sliding window, to observe the noise after processing and to the effect of the image.)

这个文档包含四种不同的功能求解非线性方程组。包括牛顿 - 拉夫逊，定点，正割，二分法方法。这项工作是我的课程的一部分，在数值计算的本科课程。它包括时序和表的打印输出进行分析和比较。有很多的观察，你可以：例如，对于一个特定的公式，一种方法可能运行的迭代次数最少，而另一个将运行更多的迭代，但计算速度最快的。(This document contains four different functions for solving nonlinear equations. Including Newton- Raphson, fixed, Secant, bisection method. This work is a part of my course in numerical undergraduate courses. It includes the timing and tables to analyze and compare the printout. There are a lot of observation, you can: For example, a specific formula, a method may be running a minimum number of iterations, while the other will run more iterations, but the calculation is the fastest.)

根据三容水箱对象本身的特性，采用带遗忘因子的辅助变量最小二乘法对其CARIMA模型参数进行了辨识，并基于辨识所得到的参数模型，用广义预测控制方法对三容水箱的液位进行了控制。实验结果表明，采用此模型的广义预测控制算法有良好的控制效果。(According to the three characteristics of the object itself- tank, using an auxiliary variable with forgetting factor least squares model parameters were CARIMA its identification, and identification of the resulting model parameters based on generalized predictive control method for three- tank liquid level control. Experimental results show that this model is generalized predictive control algorithm has good control effect.)

本程序的性能已经超过其他算法，小波包分析提取振动信号中的特征频率，采用累计贡献率的方法。( This program has exceeded the performance of other algorithms, Wavelet packet analysis to extract vibration signal characteristic frequency, The method of cumulative contribution rat.)

fscan 是在matlab里面的一个频率的扫描程序 可以对于一个特定的对象进行频谱的扫描 需要的可以自行下载(matlab at fscan are inside a frequency scanning procedure can be for a specific object to scan the frequency spectrum can download the necessary)

说明：  上传几个代码，这个是最大流和最小截算法，现在在建模，要下载一些算法，希望能通过站长的审核(From a number of code, this is the maximum flow and minimum cut-off algorithm, now in the modeling, it is necessary to download a number of algorithms, regulators hope to audit)
