Unformatted text preview: e command: view(az,el) az is the azimuth and el is the elevation of the viewpoint, both in degrees. See the viewpoint gure for an illustration of azimuth and elevation relative to the Cartesian coordiate system. Z Viewpoint Y Elevation =30 0 X Azimuth =-37.5 Default Viewpoint Example 5: View the internal Matlab peaks matrix from 4 di erent viewpoints. The rst one, (view(-37.5,30), is the default viewpoint. subplot(2,2,1) subplot(2,2,2) subplot(2,2,3) subplot(2,2,4) mesh(peaks(20)) mesh(peaks(20)) mesh(peaks(20)) mesh(peaks(20)) view(-37.5,30) view(-7,80) view(-90,0) view(-7,-10) 7 10 0 -10 20 10 00 10 10 0 -10 20 15 10 20 5 00 5 10 15 20 10 10 5 5 0 -5 -10 20 0 -5 -10 0 0 10 20 20 15 10 5 Example 5 0 5 10 15 Controlling Axes You can control the scaling and appearance of plot axis with the axis function. To set scaling for the x- and y- axes on the current 2-D plot, use this command: axis( xmin xmax ymin ymax]) To scale the axes on 3-D plot, use this: axis( xmin xmax ymin ymax zmin zmax]) In addition, returns the axis scaling to its default where the best axis limits are computed automatically axis('square') makes the current axis box square in size, otherwise a circle will look like an oval axis('o ') turns o the axes axis('on') turns on axis labeling and tic marks. axis('auto') 8...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
