You can plot surfaces and vector functions on the same figure using the hold on command. Hold off Combining vector functions and surfaces Same graph as above, but adjusting the view and the number of points in the meshgrid u=linspace(-5,5,41) Hold off Adjusting view and the meshgrid size Z2=0*x + exp(1) % the 0*x + exp(1) makes sure the output for z2 is the same size % as x and y, but only has the value of e in each component.

thus, you can do the following: u=linspace(-5,5,81) If you were to just define \( z = e \), it would only assign z to be one number, but we need the number e assigned at the z-value for each (x,y) in the domain.

This example shows how to graph a horizontal plane. Title( '3D Example with different domains') The number of points used for x and y MUST BE EQUAL thus, 51 for both of them in this example CAREFUL! this "51" number may need to be adjusted to make a smooth, nice graph and not hang the computer u=linspace(0.75,1.25,51) The command linspace(a,b,N) gives N points between a and b so linespace(0.75,1.25,81) gives 51 points between 0.75 and 1.25. This example demonstrates a way to have different x and y ranges. Hold off %%%%% DON'T FORGET TO HOLD OFF!! %%%%% Another 3D Surface Example Title( '3D Plot Example of multiple graphs') Again, you may need to adjust how many points are used to make the graph not too jagged (if number too low) or not hang the computer (number too high). Notice in this example we used a different way to get the domain for x,y using linspace as opposed to the above example. This example demonstrates how to plot more than one graph on the same figure.

The ZLIM command changes the range of the z-axis shown (you can likewise use XLIM and/or YLIM). We could have equally used the following command mesh(x,y,z) % check out the difference in the graphs! Adding axes labels, titlesĬAREFUL! One of mesh and surf may be more appropriate for different graphsįollowing labels the axes and creates a title mesh(x,y,z)

You don't want too few points in the "grid" or it will appear jagged, but too many and the computer will slow down or even hang! xd=linspace(-1,1) The meshgrid command is vital for 3D surfaces!ĭefining the domain here is even trickier than for 2D. This example shows one way to plot 3D surfaces. The main commands are mesh(x,y,z) and surf(z,y,z)
