The meshc function can be used to draw 3D mesh maps and adds a contour map to the bottom. meshz function is also used to draw 3D mesh maps, but it features a vertical “apron” around the mesh map, which extends from the edges of the mesh to the bottom and usually reaches the Z=...

MATLAB中mesh函数的使用:基于像素强度画3D密度图(create a 3D density plot based on the pixel intensity:mesh function) 所用的函数非常简单,只需要用到mesh函数,示例代码如下: 1 2 3 4 Ima=imread('F:\pathto\test.jpg'); surf_ima =surf(rgb2gray(Ima));%黑色的3D图 title('3D') mesh_ima =mesh(...
This simple function visualizes a mesh that you have created to solve some differential equation. I came up with it because I was having trouble visualizing the stretched mesh I had created for a CFD problem I was solving. Create two matrices containing the X and Y coordinates of mesh points...
