Allan Variance Calculation

这个是用于两类的带有类别的数据的线性分类器，是结构体类型如下判别 y(i) = 1 if W *X(:,i) + b >= 0 2 if W *X(:,i) + b < 0(his function classifies input data X using linear discriminant function: y(i) = argmax W(:,y) *X(:,i)+ b(y) y where parameters W [dim x nfun] and b [1 x nfun] are given in model and nfun is number of discriminant functions. In the binary case (nfun=1) the classification rule is following y(i) = 1 if W *X(:,i)+ b >= 0 2 if W *X(:,i)+ b < 0)

Involving rectifiers, AC controllers, converters.)

Koch分形曲线计算地图边界，此程序能较好的计算任意凸图形边界长度。程序计算步骤为：提取图形边界，将边界点按与中心点所成角度排序，每隔一定角度取一边界点，对选取的边界点做3次迭代Koch分形(Koch fractal curve map boundary, this procedure can be better calculated arbitrary convex graphical boundary length. The program calculation steps: to extract graphical boundary, the boundary points and the center point of the angled Sort every angle to take a boundary point, done the 3 iterations Koch fractal selected border points)
