FREEMAT 3D PLOT

As such, i tried,. 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. Your example only really defines a curve, I’m not sure how you go from that to a surface. 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. Sign up using Email and Password. Stack Overflow works best with JavaScript enabled. Is my method wrong?

Sign up using Facebook. This is how I would plot a surface: The command linspace a,b,N gives N points between a and b so linespace 0. The main commands are mesh x,y,z and surf z,y,z. 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]. 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. Basically, I have 3 parameters, x, y ,z which I have the values from experimental datas and I would like to plot them out.

This example demonstrates how to plot more than one graph on the same figure.

Plotting 3D Surfaces

Sometimes I pllt 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]. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

As I am new to it, I was just trying out. 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.

This example shows how to graph a horizontal plane. This example demonstrates a way to have different x and y ranges. Defining the domain here is even trickier than for 2D. As such, i tried. The main commands are mesh x,y,z and surf z,y,z.

Again, you may need to dreemat how many points are used to make the graph not too jagged if number too low or not hang the computer number too high. I would like to ask about 3d surface plotting.

You feeemat want too few points in the “grid” or it will appear poot, but too many and the computer will slow down or even hang! James Archer James Archer 2 4 Sign up using Facebook. 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.

Plotting 3D Surfaces L. Are you looking to plot them in 3D?

Plot 3d surface plot in matlab/freemat – Stack Overflow

This is how I would plot a surface: I do not explain every command or show everything. Post as a guest Name. The command linspace a,b,N gives N points between a and b so linespace 0. Your example only really defines a curve, I’m not sure how you go from that to a surface. Establish the domain by creating vectors for x and y using linspaceetc. Is my method wrong?

Notice in this example we used a different way to get the domain for x,y using linspace as opposed to the above example.

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