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...
% 创建网格点坐标 [X, Y] = meshgrid(-2:0.2:2, -2:0.2:2); % 计算每个网格点的高度 Z = X .* exp(-X.^2 - Y.^2); % 绘制三维表面图 surf(X, Y, Z) % 设置坐标轴标签 xlabel('X') ylabel('Y') zlabel('Z') % 添加标题 title('3D Surface Plot') 复制代码 运行上述代码会绘制...
The MATLAB plot gallery provides examples of many ways to display data graphically in MATLAB. You can view and download source code for each plot, and use it in your own MATLAB project.
such as as the bottom surface of a three-dimensional surface plot, or perform two-dimensional interpolation tasks. Its basic syntax is [X, Y] = meshgrid(x, y), where x and y are two vectors representing points on the X-axis and Y-axis respectively. The function returns two matrices X...

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...
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 ...
