The command plot3(x,y,z) in MATLAB help to create three-dimensional plots. 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. 3-D Plots. Mesh Plot. Basic 3D Surface Example using SURF. Using the slice() function may help to plot the 3D matrix as slices in a 3D plot. By default, the color of the mesh is proportional to the surface height. The meshgrid command is vital for 3D surfaces! Defining the domain here is even trickier than for 2D. The mesh function creates a wireframe mesh. 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 general form of the command is: plot3(x,y,z,‘line specifiers’) where, The following three inputs dictate the method used to slice the matrix. 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 = 3-D plots are useful to present data having more than two variables. The matrix is a 4D matrix that is a function of x y z and time, where at each … 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. Use plots to visualize data. Using Slices of a Matrix to Create 3D Plot. How to Make 3D Plots Using MATLAB. I'm trying to plot an animated 3D plot from some data that I've calculated. 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. Until you use hold off or close the window, all plots appear in the current figure window. Plot continuous, discrete, surface, and volume data. plot3(X,Y,Z) plots coordinates in 3-D space. To add plots to an existing figure, use hold on. Three-dimensional plots typically display a surface defined by a function in two variables, z = f(x,y). 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. Given that I saw the question before the multiple edits. The slice() function takes three additional inputs along with the matrix/volume to be plotted. Create plots programmatically using graphics functions or interactively using the Plots tab at the top of the MATLAB ® desktop. For example, you can compare sets of data, track changes in data over time, or show data distribution. 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. z = peaks(25); figure mesh(z) Surface Plot. 2-D and 3-D Plots. MATLAB 3D Plots. In general, three-dimensional plots are helpful for displaying two types of … This example shows how to create a variety of 3-D plots in MATLAB®. MATLAB also includes a wide variety of three-dimensional plots that can be useful for displaying certain types of data. This example shows one way to plot 3D surfaces.
