DBchart 画图 进行时间等分 时间等分(dbchart )

自己编的可输入数据的，三次B样条曲线程序源码(nurbs spline)

中点画圆与中点画直线 二维图形变换 多边形填充 计算机图形学实验(The midpoint Circle draws line in two-dimensional graphics transform polygon fill, computer graphics experiments)

很好的PSCAD调用.f小程序。有助于初学者学习(PSCAD good call. F applet. Help beginners learn)

说明：  实现中点画圆 在qt平台上实现 语言为c++ 是计算机图形课上的代码 可以编译通过的(realize draw the point in the middle)

说明：  使用MFC实现画摇杆的效果，同时画出摇杆的运动轨迹(Use MFC to realize the effect of drawing the rocker and draw the movement track of the rocker at the same time)

GMT是一个很强大的地学绘图软件，应用于很多专业，很实用，这是一篇很好的GMT入门教程(GMT is a very powerful geoscience mapping software, used in many professional and very practical, this is a good introductory tutorial GMT)

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)
