Create a contour plotof values from the peaks function. [X,Y,Z] = peaks(3); [C,h] = contour(X,Y,Z); Access the contourmatrix using either the output argument C or the ContourMatrix property of the contour object (h.ContourMatrix). The contour matrix contains definitions for eachof ...
image intensity values are equal to a constant. You can create a contour plot of the data in a grayscale image using theimcontourfunction. This function is similar to thecontourfunction in MATLAB®, but it automatically sets up the axes so their orientation and aspect ratio match the image...
%% 方式一:统一设置图例 legend('cos(x)','cos(2x)') % 设置图例,顺序与绘图一致 %% 方式二 plot(x,y1,'DisplayName','cos(x)') % 绘图时设置显示名称 legend %% legend({'cos(x)','cos(2x)','cos(3x)','cos(4x)'},'Location','northwest','NumColumns',2) % 在坐标区的西北角创建一个...
Create a contour plot of the peaks function, and specify the dashed line style. Get [X,Y,Z] = peaks; contour(X,Y,Z,'--') Contours with Labels Copy Code Copy Command Define Z as a function of two variables, X and Y. Then create a contour plot of that function, and display the...
I have made a contour plot in matlab (See code). And I want to find the contour line where the value is equal to 1. Now I just have found it approximately between to lines contour plot: Can this be done? For example if I want to plot 5 contour lines from the values 0 to 1 Up...
函数plot、plot3、contour和contour3不使用颜色映象,它们使用列在plot颜色和线形表中的颜色。而大多数其它绘图函数,比如mesh、surf、fill、pcolor和它们的各种变形函数,使用当前的颜色映象。 接受颜色参量的绘图函数中的颜色参量通常采用以下三种形式之一:(1)字符串。代表plot颜色或线型表中的一种颜色,比如,’r‘代表...
不知道是不是需要符合要求，看个例子吧 [x,y] = meshgrid(-2:.2:2,-1:.15:1);z = x .* exp(-x.^2 - y.^2); [px,py] = gradient(z,.2,.15);contour(x,y,z), hold on quiver(x,y,px,py), hold off, axis image ...
Then, plot the 3D contour slices of V using ThemeCopy % Sample data for demonstration x = rand(20, 1) * 10; y = rand(20, 1) * 10; z = rand(20, 1) * 10; V = sin(x) + cos(y) + z; % Create a grid and int...
function = contour(varargin)CONTOUR Contour plot.CONTOUR(Z) is a contour plot of matrix Z treating the values in Z as heights above a plane. A contour plot are the level curves of Z for some values V. The values V are chosen automatically.CONTOUR(X,Y,Z) X and Y ...
