The surface plot only colors the mesh surface. statement mesh(X,Y,Z) generates the mesh plot of the function.Then, the matrices X and Y are evaluated in function Z=X+Y.statement =meshgrid(x,y) used to transforms the domain specified by two vectors x and y, into matrices X and Y.statements x=-1:0.1:3 and y=1:0.1:4 are used to create two vectors x and y.
3d plot matlab how to#
The example below will show you how to create a mesh plot in MATLAB.Īim(1): To make a mesh plot of the function z=x+y, over the domain
The general form of the mesh command is: mesh(x,y,z) They plot a graph over the functions in the form of z = f(x,y), where x and y are the independent variables and z is the dependent variable.
3d plot matlab code#
(0 ≤ t ≤ 50) x = sin(t) y = cos(t).Ĭreate a script file in MATLAB and type the following code – x=sin(t) y=cos(t) z=t The example below will show you how to use plot command in MATLAB.Īim(1): To plot a curve for variables x, y and z as the function of time t lies between 0 to 50 sec. The general form of the command is: plot3(x,y,z,‘line specifiers’) The command plot3(x,y,z) in MATLAB help to create three-dimensional plots.
3d plot matlab Patch#
Patch('Faces',fac,'Vertices',vert,'FaceColor','r') % patch functionAfter reading the MATLAB 3-D plots topic, you will understand how to create 3-d plots as a surface plot or mesh plot in MATLAB.ģ-D plots are useful to present data having more than two variables. % specify patch (polygons) in patch() function % define the arbitrary polygon(patch) using the vertice number(index) you defined above. % specifies all the vertices that comprises the object you want to draw '.' erase this and retype '.' in your matlab code if you get errors. Note : If you copy and paste this code as it is, '.' may cause errors in Matlab. * sin(azimuth) Įx) This has been tested only in Matlab (Not sure patch() is supported by Octave) + Y.^2 - 2.*X = 3Įx) This has been tested only in Matlab (Not sure scatter3 is supported by Octave) =contour(X,Y,Z,) Ĭontour(X,Y,Z,) % implicit plot for X.^2. View(angle_around_z_axis, angle_around_y_axis) // angle in degree I haven't completed 'what I think is the minimum set' yet and I hope I can complete within a couple of weeks.
If you getįamiliar with these minimal set of functionality, you would get some 'feeling' about the tool and then you would make sense out of the official document from Mathworks or GNU Octave which explains all the functions but not so many examples. My purpose is to provide you the set of basic commands with examples so that you can at least read the most of sample script you can get from here and there (e.g, internet) without overwhelming you.
There are huge number of functions which has not been explained here, but I would try to list those functions which are most commonly used in most of matlab sample script you can get. I would try to list those commands that can work both with Matlab and Octave). I don't think it has 100% compatability between Octave and Matlab, but I noticed that most of basic commands are compatible.
3d plot matlab free#
(Octave is a GNU program which is designed to provide a free tool that work like Matlab. : In this page, I would post a quick reference for Matlab and Octave.
