克里金插值计算，一种拟合算法，主要用于等值线应用。(Kriging interpolation calculation, a fitting algorithm, mainly for the application of contour lines.)

CAD批量打印源码程序，例程结合易语言应用接口支持库、拖放支持库、扩展功能支持库，创建Autocad.Application对象，实现CAD对象的属性、方法，可以批量打印。(CAD batch printing source programs, routines combined with easy language support library application interface , drag and drop support libraries , extensions support library , create Autocad.Application object implementing the CAD object s properties , methods, you can batch print .)

实现本机流量监控绘图，测试可用，方便安全(Netflow monitoring)

该程序可以绘制出扇形，并且带有黑色边框。(The program can draw out the fan, and with a black border.)

VB编写的画图板，使用方便可以帮助代码学习。。(VB prepared the drawing board, easy to use can help the code to learn. .)

该程序实现了图形学中的一些算法，如画线、画圆，填充、直线多边形、扫描转换，扫描线消隐算法以及一个简单的Gouraud光照模型。(the realization of a number of graphics algorithms, painting lines, the Circle, filling, linear polygon scan conversion, Lines scanning algorithm and a simple scan illumination model.)

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)

实现三角形的类、用类的继承关系编写程序描述下图1中的类层次(Write a class Triangle Triangle、Class inheritance relationships with programming description Figure 1 class hierarchy)

cad中可以像cass一样划线,具有换向，隔点闭合等功能！(cad cass huaxian)

国外高手写的可以读写dxf格式信息。值得收藏(Foreign experts to write the information can be read dxf format. Worth collecting)
