fsurf(f) creates a surface plot of the symbolic expression f(x,y) over the default interval [-5 5] for x and y. example fsurf(f,[min max]) plots f(x,y) over the interval [min max] for x and y. example fsurf(f,[xmin xmax ymin ymax]) plots f(x,y) over the interval ...
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 surface plot of the function z = f(x,y) over the default interval [-5 5] for x and y.
% 改善曲面着色效果 shading interp; % 显示图形 axis tight; % 自动调整轴范围以紧密显示数据 view(3); % 设置视角为三维视角 grid on; % 显示网格 % 如果需要保存图形,可以使用saveas函数 % saveas(gcf, 'threed_surface_plot.png'); 将以上步骤整合在一起,你可以得到完整的MATLAB代码来绘制三维曲面图...
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...
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 ...
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...
