分形曲面的matlab简单程序，已经测试过。(Fractal surface matlab simple procedure, has been tested.)

PLL锁相环的搭建，通过坐标变换实现锁相(PLL Phase-Locked Loop)

1 设计一个ＦＩＲ数字低通滤波器， 满足一组模拟滤波器的指标参数；分别采用三角窗、hamming窗、blackman窗和kaiser窗进行设计。比较不同窗的设计效果。要求描绘滤波器的脉冲响应、窗函数以及滤波器的幅频和相频响应曲线。 2. 用上述设计滤波器完成几组给定信号的滤波。 3.设计数字高通、带通、带阻滤波器，要求描绘滤波器的脉冲响应以及滤波器的幅频和相频响应曲线。 (1、A design of a FIR digital low-pass filter, analog filters to meet the target of a group of parameters were used triangular window, hamming window, blackman windows and kaiser window design. Window to compare different design effect. Requirements described impulse response filter, window function and the filter amplitude-frequency and phase frequency response curve. 2. Using the above filter was designed to complete several sets of a given signal filtering. 3. Design of digital high-pass, band pass, band-reject filter, the filter impulse response described demand as well as the filter amplitude-frequency and phase frequency response curve.)

ML-KNN实现过程，包括训练和测试两个过程(the process of ML-KNN, including training and testing )

用于信号处理的MATLAB基本操作，离散时间的信号，典型序列(MATLAB for the basic operation of signal processing, discrete-time signal, a typical sequence)

在matlab上运用有限时域差分法模拟二维光子晶体(the simulation of tm mode in two-dimensional photonic crystals using FDTD)

这是matlab中常用的快捷键，可以使你使用matlab更顺手。(This is the common shortcut keys of matlab.It can make you use matlab better.)

使用svm进行数据的预测，首先进行pca对数据进行主元分析，提取有用信息，结果显示数据拟合效果非常好(SVM is used to predict data. first, PCA is used to analyze the data and extract useful information. the results show that the data fitting effect is very good.)

希望对你有帮助，包含了整个的过程，我研究了好久，收获很大。(I hope it can help you, contains the whole process, I studied for a long time and fruitful.)
