系统辨识作业 考虑如下模型 z(k)-1.5z(k-1)+0.7z(k-2)=u(k-1)+0.5u(k-2)+v(k) 其中v(k)是均值为0，方差为1的白噪声。根据模型生成数据，采用递推最小二乘法对模型参数进行辨识，要求绘出各参数随时间的变化曲线。 ("System identification" computer test 。Consider the following model Z (k) to 1.5 of z (k- 1)+ 0.7 z (k- 2) = u (k- 1)+ 0.5 u (k- 2)+ v (k) The v (k) is the mean to 0, the white noise variance 1. Generate data according to the model, the recursive least squares method is adopted to model parameters are identified, draw the parameters changing with time curve. )

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 .)

基于PSCAD的UPFC模型，采用前馈解耦策略，有功无功基本独立控制，波形较好(Unified Power Flow Control Model based on PSCAD)

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.)

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.)
