Matlab绘图教程(大量实例PPT)，可供初学者绘图使用，简单方便。(Matlab graphics tutorials (large number of examples PPT), drawing for beginners to use, simple and convenient.)

自己在PSCAD中搭建的PLL，用的是分立元件搭建的，有助于自己学习以及编程实现，已经与自带的PLL进行对比，验证了正确性(PSCAD built himself in the PLL, using discrete components built to help you learn and programming has been compared with the built-in PLL, verify the correctness)

信号频谱分析 1. 观测已知方波信号、正弦波信号的频谱 分析频率为4KHz、8KHz的占空比为50 的方波信号、正弦波信号的频谱。记录所得频谱图。 观测实时模拟信号（语音）的频谱 用音频设备采集一段语音，将语音存为.wav格式。对wav文件作分段傅里叶变换分析。语音是分音节的，应把它分段分析，而且实际运用中的数字信号处理的FFT的点数是有限的，一般只能达到千点。用傅里叶反变换IFFT，从频域恢复信号。画出频谱图和语音波形图(Signal spectrum analysis 1. Observing a known square-wave signal, sine wave signal frequency spectrum analysis 4KHz, 8KHz for the 50 duty cycle square wave signal, sine wave signal frequency spectrum. The recorded frequency spectrum. Observing real-time analog signal (voice) of the spectrum collected with the audio devices section of voice, voice saved as. Wav format. Wav file of the sub-Fourier transform analysis to make. Speech is divided into syllables, it should be sub-analysis, and practical application of digital signal processing of the FFT points is limited, generally only reach 1000 points. Fourier inverse transform IFFT, to restore the signal from the frequency domain. Draw maps and voice waveform spectrum)

分形几何是数学领域里新兴的课题,如果将图形的每个元素按某种规则进行变形,得到新的图形,以此类推,进行若干次变形后得到的图形就是分形图形。本程序实现分形图。(Fractal geometry is the mathematical field of emerging issues, if the graphics of each element according to certain rules of deformation, new graphics, and so on, to carry out a number of graphics after deformation is fractal graphics. This procedure realize fractals.)

说明：  绘制磁滞回线，模拟磁滞回线产生的过程，便于理论分析建模(Drawing hysteresis loops to simulate the process of hysteresis loops is convenient for theoretical analysis and modeling.)

绘图板软件，实现了文件打开，矢量保存，各种线和图形的绘画，颜色的更换。(it is a paint pad,you can use it to change your color,your paint,and can save yours.)

均为matlab的画图程序，不等式组，分叉图，吸引子，敏感性等( matlab drawing program, about inequalities, bifurcation diagram, attractors, sensitivity)

C/c++趣味程序百例(献给C/C++初学者) 1.绘制余弦曲线 2.绘制余弦曲线和直线 3.绘制圆 4.歌星大奖赛 5.求最大数 6.高次方数的尾数 7.阶乘尾数零的个数 8.借书方案知多少 9.杨辉三角形 10.数制转换 11.打鱼还是晒网 12.抓交通肇事犯 13.该存多少钱 14.怎样存钱利最大 (The C/c++ interesting program one hundred cases (dedicated C/C++, beginners) 1.
