The code for Surface is 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...
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...
This MATLAB function creates a three-dimensional surface plot, which is a three-dimensional surface that has solid edge colors and solid face colors.
which lays the foundation for the visualization and processing of two-dimensional spatial data. Meshgrid is particularly useful when you need to draw graphics in two-dimensional space, such as as the bottom surface of a three-dimensional surface plot, or perform two-dimensional interpolation tasks. ...

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...
