RGB = imread ('ngc6543a.jpg'); image (RGB); axis image; This table summarizes display methods for the three ... First, plot a surface and display the box outline around the axes. By default, the outline appears around the back planes of the axes because the BoxStyle property of the axes is set to 'back'. [X,Y,Z] = peaks; surf (X,Y,Z) box on. Next, display the outline around the entire axes by setting the BoxStyle property to 'full'.Scale and Rotate. Scale the surface by the factor 3 along the z-axis.You can multiply the expression for z by 3, z = 3*z.The more general approach is to create a scaling matrix, and then multiply the scaling matrix by the vector of coordinates.Create a tiled chart layout in the 'flow' tile arrangement, so that the axes fill the available space in the layout.
