Does anyone know how to plot surface plot in matlab using three vectors? since i dun have a function for me to integrate, the one with me is the surface plot (k)... is it wrong if i use the integral2 to compute the volume of k? Here's a description of two easy ways to make surface plots in Matlab, including step-by-step instructions. To plot 3D graphs, you need to have 3 of variables. Christiaan on … You can do this in Matlab with ‘meshgrid()’ command. Facebook. z = peaks(25); figure mesh(z) Surface Plot. Attached a sample of my data, where: X range= 2200:50:3800 Y range= 0:.005:0.2 Z range= 0:10:500 During each loop I extract my objective function f which I … By default, the color of the mesh is proportional to the surface height. I would like to create something that resembles a surface plot, but I can not convert my Z into a matrix. Negative values does not seem to work in camera option. MATLAB: 3D surface plots. The function also uses Z for the color data in … I'm having trouble plotting a curve/surface of best fit through data points. 2. Viewed 5k times 1. Let’s look at the following code: syms x; fsurf(tan(x)); Rather than showing the individual data points, surface plots show a functional relationship between a designated dependent variable (Y), and two independent variables (X and Z). Please consider donating to Black Girls Code today. By entering the surf function, it will generate a 3-D surface plot. Plots can be created using graphic functions or interactively using the MATLAB Desktop. I need to find several (~5) peaks in a 3D surf plot; tried imregionalmax but it's giving me too many maximums and I can't find a way to control it. Specify the colors for a surface plot by including a fourth matrix input, C.The surface plot uses Z for height and C for color. 3D Surface Plots Introduction Surface plots are diagrams of three-dimensional data.
