# Matlab surface meshing

Meshing is the process of converting the continuous domain into the discrete domain for solving the equations. For discretizing surfaces, typically either triangles or rectangles are used. Antenna Toolbox™ uses triangular element for meshing as it conforms better for arbitrary shaped surfaces. The triangles are used to approximate the surface current using the Rao-Wilton-Glisson (RWG) basis functions. To get an accurate result, ensure that large number of triangles are present in the. This example shows how to create a variety of 3-D plots in MATLAB®. Changing Surface Properties. This example shows how to get properties of a surface plot in MATLAB® and change the property values to customize your plot. Representing Data as a Surface. You can visualize matrix data on a rectangular grid using surface plots

1. example. pdeplot3D ( ___,Name,Value) plots the surface mesh, the data at nodal locations, or both the mesh and data, depending on the Name,Value pair arguments. Use any arguments from the previous syntaxes. h = pdeplot3D ( ___) returns a handle to a plot, using any of the previous syntaxes
2. However I've heard that there is also another method, which requires software available at my univeristy - MatLab. The idea is to write a script that would put a surface mesh on my 3D model and allow export in COMSOL-friendly format (LiveLink is not possible in this case - COMSOL is running on different university computers than MatLab)
3. Specify the colors for a surface plot by including a fourth matrix input, CO. The surface plot uses Z for height and CO for color. Specify the colors using truecolor, which uses triplets of numbers to stand for all possible colors. When you use truecolor, if Z is m-by-n, then CO is m-by-n-by-3. The first page of the array indicates the red component for each color, the second page indicates the green component, and the third page indicates the blue component
4. You can use the meshgrid function to create the X and Y matrices. The XData property of the Surface object stores the x -coordinates. Example: X = [1 2 3; 1 2 3; 1 2 3] Example: [X,Y] = meshgrid (-5:0.5:5) Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64
5. MATLAB can create different forms of surface plots. Mesh plots are wire-frame surfaces that color only the lines connecting the defining points. Surface plots display both the connecting lines and the faces of the surface in color. This table lists the various forms
