Notice in this example we used a different way to get the domain for x,y using linspace as opposed to the above example. Email Required, but never shown. Create a “grid” in the xy-plane for the domain using the command meshgrid Calculate z for the surface, using component-wise computations Plot the surface. Defining the domain here is even trickier than for 2D. Plotting 3D Surfaces L. Your example only really defines a curve, I’m not sure how you go from that to a surface.

This page will not show all of them; it will show the way that is the most customizable and can be easily extended to more complicated settings like parametric equations, 3D, etc. Email Required, but never shown.

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. This has a lot of stuff; read the contents carefully!

The command linspace a,b,N gives N points between a and b so linespace 0.

Are you looking to plot them in 3D? This example demonstrates how to plot more than one graph on the same figure.

Hm, as far as i can tell, it should give you an error since Z has to be a matrix and you’ve only defined a vector. Plkt main commands are mesh x,y,z and surf z,y,z.

This is how I would plot a surface: Your example only really defines a curve, I’m not sure how you go from that to a surface.

See if that does what you want. 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. Establish the domain by creating vectors for x and y using linspaceetc. This example demonstrates a 3f to have different x and y ranges.

Plotting 3D Surfaces L. I do not explain every command or show everything. You don’t want too few freemay in the “grid” or it will appear jagged, but too many and the computer will slow down or even hang! Use Mozilla Firefox or Safari instead to view these pages. Post llot a guest Name.

It sounds like you need to start with plot3as you’re just describing a set of points in 3D, rather than points on pllot mesh or surface.

James Archer James Archer 2 4 Is my method wrong? Create a “grid” in the xy-plane for the domain using the command meshgrid Calculate z for the surface, using component-wise computations Plot the surface. As I am new to it, I was just trying out.

There are several ways to produce graphs of functions. Sometimes I use axis limets to make the plot look nicer eliminates the unneeded white area’s ; for this set of data I could use xlim [6 11] and ylim [2 6].

This example shows how to graph a horizontal plane.

I would like to ask about 3d surface plotting. This has a lot of stuff; read the contents carefully! It is up to you to experiment and look up these commands to better understand them. This is also a learn-by-example page. Defining the domain here is even trickier than for 2D. As such, i tried.

Basically, I have 3 parameters, x, y ,z which I have the values from experimental datas and I would like to plot them out.
