clabel(C,h,v) labels the contour levels specified by vector v. example clabel(C,h,'manual') labels the locations you select with the mouse. Click the mouse or press the space bar to label the contour closest to the center of the crosshair. Press the Return key while the cursor is ...
To interactively select the contours to label using the mouse, pass themanualoption toclabel, for example,clabel(C,h,'manual'). This command displays a crosshair cursor when the mouse is within the figure. Click the mouse to label the contour line closest to the cursor. ...
Then display a filled contour plot of Z, letting MATLAB® choose the contour levels. Get Z = peaks; contourf(Z) Contours at Ten Levels Copy Code Copy Command Define Z as a function of two variables, X and Y. Then display contours at 10 levels of Z. Get x = linspace(-2*pi,2...
linspace(-2*pi, 2*pi, 100); y = linspace(-2*pi, 2*pi, 100); % Create the X-Y grid [X, Y] = meshgrid(x, y); % Calculate the Z variable (for example, sine of the distance from the origin) Z = sin(sqrt(X.^2 + Y.^2)); % Generate the contour plot contour(X, Y,...
contour(X,Y,Z,'r--'); % 使用红色虚线绘制等高线 填充等高线之间的区域 使用contourf 函数可以填充等高线之间的区域: contourf(X,Y,Z); colorbar; % 通常与 colorbar 一起使用来显示颜色映射 手动指定等高线级别 你可以手动指定等高线的级别: levels = [-5:-1 0 1:5]; % 定义等高线级别 contour(X...
contour3(X,Y,Z,50) Contours at Specific Levels with Labels DefineZas a function of two variables,XandY. Then plot the contours atZ = [-.2 -.1 .1 .2]. Show the contour labels by setting theShowTextproperty to'on'. [X,Y] = meshgrid(-2:0.25:2); Z = X.*exp(-X.^2-Y.^2)...
在Matlab中，使用contour plot绘制等值线图是一种常见的方法。例如，可以绘制函数z = x * exp(-x^2 - y^2)的等值线图。首先，创建网格数据，这可以通过meshgrid函数实现：[x, y] = meshgrid(-2:.2:2, -1:.15:1);然后计算z值：z = x .* exp(-x.^2 - y.^2);接下来，使用...
[r,theta,x,y,streamline,pressure]=flowAroundCylinder();contourLevels=20;LineWidth=1;[~,c]=contourf(x,y,pressure,...contourLevels,... % Specify a scalar integer number of contour levels"LineWidth",LineWidth);% Specify the contour line widthaxis([-5,5,... % x-axis limits-5,5]);% ...
This MATLAB function plots the contour lines of the function z = f(x,y) for constant levels of z over the default interval [-5 5] for x and y.
contour3函数:3维等高线图,等高线不再投影到x-y平面 contour3(x,y,z,levels,‘ShowText’,‘on’) xlabel(‘x轴’); ylabel(‘y轴’); zlabel(‘z轴’); % 加上坐标轴的标签 4 .绘制符号函数图 plot3函数 (类似于plot函数,实际上可以认为画的是三维空间下的折线图) ...
