The surf function is used to draw three-dimensional surface maps, with the complementary surfaces between grid lines filled with color. The basic syntax is surf(x,y,z). where x and y are coordinate matrices, usually generated by the meshgrid function, that define the locations of mesh points...
The fsurf() function is a very useful function in MATLAB for plotting 3D surface maps. It accepts a mathematical expression as input and automatically computes a corresponding 3D surface plot. This function is great for visualizing complex mathematical functions, especially those where it is not ea...
This MATLAB function creates a surface plot of the function z = f(x,y) over the default interval [-5 5] for x and y.
title('3D Surface Plot with meshgrid and surf'); 在这个示例中,X和Y是通过meshgrid生成的二维矩阵,而Z是由函数Z = X.^2 + Y.^2计算得出的高度值。这段代码生成了一个抛物面。 三、SURF、绘制三维曲面 surf函数用于绘制三维曲面图。与plot3不同,surf不仅可以显示三维曲面,还能通过颜色来表达数据的第四维度。

surf(), surf(X,Y,Z) creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid face colors. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and Y. The color of the surface ...
