set(2,'position',[100,100,1000,600])中这是什么意思，高手指点指点，谢谢

from matlab help:
Figure position. This property specifies the size and location on the screen of the figure window.
or
Position of axes. A four-element vector specifying a rectangle that locates the axes within the figure window. The vector is of the form: [left bottom width height]
where left and bottom define the distance from the lower-left corner of the figure window to the lower-left corner of the rectangle. width and height are the dimensions of the rectangle. All measurements are in units specified by the Units property.
When axes stretch-to-fill behavior is enabled (when DataAspectRatioMode, PlotBoxAspectRatioMode, CameraViewAngleMode are all auto), the axes are stretched to fill the Position rectangle. When stretch-to-fill is disabled, the axes are made as large as possible, while obeying all other properties, without extending outside the Position rectangle

[U,S,V]=svd(P(:,:,round(f*1024/2000)+1));  
            Ph=180*(abs(angle(U(:,1)))-pi/2)/pi;
            disp(Ph');
            Md=abs(U(:,1)).*sign(Ph);
            Md=Md/max(abs(Md));
            figure(3)
            fig=3;
            hold on
            whitebg(3,'k')                           
            set(3,'position',[200,100,1000,300])
            plot(Md,'y','linewidth',8)
            plot([0,1],[0,0],'w')
            axis([0,1,-1.2,1.2])

Md=abs(U(:,1)).*sign(Ph);中“.*”是什么意思？
set(3,'position',[200,100,1000,300])中，括号里面的各个量代表什么？
谢谢
