contoursliceExamplesThis example uses the flow data set to illustrate the use of contoured sliceplanes (type help flow for more information on this data set). Notice that thisexample:• Specifies a vector of length = 9 for Sx, an empty vector for the Sy, and ascalar value (0) for Sz. This creates nine contour plots along the x directionin the y-z plane, and one in the x-y plane at z = 0.• Uses linspace to define a ten-element linearly spaced vector of values from-8 to 2 that specifies the number of contour lines to draw at each interval.• Defines the view and projection type (camva, camproj, campos)• Sets figure (gcf) and axes (gca) characteristics.[x y z v] = flow;h = contourslice(x,y,z,v,[1:9],[],[0],linspace(-8,2,10));axis([0,10,-3,3,-3,3]); daspect([1,1,1])camva(24); camproj perspective;campos([-3,-15,5])set(gcf,'Color',[.5,.5,.5],'Renderer','zbuffer')set(gca,'Color','black','XColor','white', ...'YColor','white','ZColor','white')box on2-111
