此源码提供了ssvm的完整的matlab源代码，主要运用UD设计原理对参数搜索提高了效率。(This source provides a complete ssvm the matlab source code, the main design principle of the use of UD on the parameters of the search efficiency.)

用牛顿拉夫逊法的极坐标形式计算电力系统潮流(Newton Raphson method polar form power flow calculation)

实现对欧洲足球冠军联赛16强抽签的仿真，球队采用本赛季产生的16支球队。(Implementation of European football simulation, 16 of the champions league draw teams using the 16 teams this season.)

编写M文件，创建如下图形窗口，分别绘制如下图所示的曲线。 （1）曲线y=sin(t)sin(9t)，要求采用红色，点线。横坐标取值范围[0~ ]，标注x轴、y轴并加标题。 （2）一组余弦曲线，其振幅分别为0.4，0.6和0.8。横坐标取值范围[0~2 ]。添加图例与标题。进入图形编辑状态，调整图例的位置。 （3）分别绘制peaks函数的曲面图和网格线图。对曲面图做平滑处理，并添加标题与colorbar。 (Write M file, create the following graphics window, curves were plotted as shown below. (A) the curve y = sin (t) sin (9t), require the use of a red dotted line. The abscissa in the range [0 ~  ], labeled x-axis, y-axis and a title. (2) a set of a cosine curve, and the amplitude was 0.4, 0.6, 0.8. Abscissa value range [0 ~ 2  ]. Add a legend and title. Into the graphical editing mode, adjust the position of the legend. (3) were drawn surface chart peaks function and grid line graph. Surface charts do for smoothing and add titles and colorbar.)
