2012年5月PSCAD/EMTDC电力仿真技术交流会的PPT，是学习风电的很好资料(May 2012 PSCAD/EMTDC power simulation technology Seminar PPT is a good learning wind power)

说明：  在大型机上使用NCL画WRF模式运转结果的雨量图(Use NCL to draw rainfall map of WRF mode operation result)

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. )

本程序是计算机图形学课程设计的程序，包含用各种算法绘制直线、圆、曲线，填充，剪裁等，有助于计算机图形学的学习与实践。(This procedure is a computer graphics curriculum design process, including the use of various algorithms to draw lines, circles, curves, filling, cutting, etc., help to learn and practice of computer graphics.)

这是在MATLAB-2008a环境下编写的NURBS曲面生成程序，可以通过调整控制顶点和各个顶点的权重来调整曲面的形状。(This is a MATLAB-2008a environment, prepared by the NURBS surface generation program, you can adjust the control points and weights of all vertices to adjust the surface shape.)
