The general form of the command is: plot3(x,y,z,‘line specifiers’) where, After 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. 3-D plots are useful to present data having more than two variables. Given that I saw the question before the multiple edits. Basic 3D Surface Example using SURF. Using MATLAB, a series of 3-D plot function data suitable for aeronautical use, that enables coordinate analysis of various trajectories in space, aiding marine navigation via satellites and GPS, all are possible via this technology. The command plot3(x,y,z) in MATLAB help to create three-dimensional plots. I'm trying to plot an animated 3D plot from some data that I've calculated. Create a 3 by 3 matrix as the first page in a 3-D array (you can clearly see that we are first creating a 2D matrix) A = [11 2 7; 4 1 0; 7 1 5] Add a second page now. z = peaks(25); figure mesh(z) Surface Plot. The meshgrid command is vital for 3D surfaces! 2-D and 3-D Plots. Defining the domain here is even trickier than for 2D. To plot multiple sets of coordinates on the same set of axes, specify at least one of X , Y , or Z as a matrix and the others as vectors. This example shows one way to plot 3D surfaces. Create plots programmatically using graphics functions or interactively using the Plots tab at the top of the MATLAB ® desktop. This can be done by assigning one more 3 by 3 matrix with index value 2 in the third dimension; A(: , :, 2) = [1 2 5 ; 4 4 6 ; 2 8 1] A[3×3] A = MATLAB also includes a wide variety of three-dimensional plots that can be useful for displaying certain types of data. Three-dimensional plots typically display a surface defined by a function in two variables, z = f(x,y). To add plots to an existing figure, use hold on. For example, you can compare sets of data, track changes in data over time, or show data distribution. plot3(X,Y,Z) plots coordinates in 3-D space. Until you use hold off or close the window, all plots appear in the current figure window. The mesh function creates a wireframe mesh. By default, the color of the mesh is proportional to the surface height. Use plots to visualize data. Using the slice() function may help to plot the 3D matrix as slices in a 3D plot. 3-D Plots. MATLAB 3D Plots. The following three inputs dictate the method used to slice the matrix. How to Make 3D Plots Using MATLAB. To plot a set of coordinates connected by line segments, specify X , Y , and Z as vectors of the same length. By default, MATLAB® clears the figure each time you call a plotting function, resetting the axes and other elements to prepare the new plot. Using Slices of a Matrix to Create 3D Plot. To evaluate z, first create a set of (x,y) points over the domain of the function using meshgrid. The matrix is a 4D matrix that is a function of x y z and time, where at each … This example shows how to create a variety of 3-D plots in MATLAB®. In general, three-dimensional plots are helpful for displaying two types of … Whether it's for research, a school assignment, or a work presentation, 3-D plots are great for visualizing what a complicated set of data looks like. Plot continuous, discrete, surface, and volume data. The slice() function takes three additional inputs along with the matrix/volume to be plotted. Mesh Plot.
