MATLAB读取.mat文件,就可以直接运用这个Colormap: % Load .mat file S = load('RdBu_cmap.mat'); cmap = S.cmap; % Get the colormap array % Simple diverging data [x, y] = meshgrid(linspace(-5,5,300), linspace(-5,5,300)); Z = x + y; % Plot figure; imagesc(Z); axis image; ...
使用预定义的颜色映射:MATLAB 提供了一些预定义的颜色映射(colormap),如 jet、hot、cool 等。虽然这些颜色映射通常用于绘制曲面图,但也可以用于设置线条颜色。不过,这种方法通常不直接用于 plot3,而是更多地在 surf、mesh 等函数中使用。 3. 示例代码 以下是一个使用 plot3 函数并设置线条颜色的示例代码: matlab ...
最基本的三维图像函数为plot3,它将二维绘图函数plot的有关功能扩展到三维空间。其调用格式为:plot3(x1,y1,z1,选项1,x2,y2,z2,选项2,...)在Matlab命令窗口中输入代码,绘制出图像。 The most basic three-dimensional image function is plot3, which extends the related functions of the two-dimensional d...
给⼤家⼀个⾮常好⽤的matlab程序（⼀个figure中画多幅图，colormap如 何设置）function freezeColors(varargin)% freezeColors Lock colors of plot, enabling multiple colormaps per figure. (v2.3)% % Problem: There is only one colormap per figure. This function provides % an easy sol...
Then display two filled contour plots with different colormaps. Get tiledlayout(2,1) ax1 = nexttile; contourf(peaks) colormap(ax1,hot(8)) ax2 = nexttile; contourf(peaks) colormap(ax2,pink) Return the colormap values used in the upper plot by passing ax1 to the colormap function. ...
首先，通过map()函数创建地图对象，并获取每个区域的名字以及顺序。然后，在每个区域的名字和顺序后面，加...
plot(x, y, 'k-'); hold on; % 绘制误差棒 errorbar(x, y, yerr, 'k.'); hold off; % 添加图例、坐标轴标签和标题 legend('Data', 'Location', 'best'); xlabel('x'); ylabel('y'); title('Sin Function with Error Bars');
I have got 2 matrices x and y. For each x(i,:) y(i,:) I have got an array z. Now I want to draw them color coded like in a scatter plot corresponding with z and I also also want to have a colorbar, which is linked to the according color. At the same moment I want to...
resultant image%img=padarray(img,[11],'symmetric','both');[row,col]=size(img);dimg=zeros(row,col);switch(direction)case'dx',dimg(:,2:col-1)=(img(:,3:col)-img(:,1:col-2))/2;case'dy',dimg(2:row-1,:)=(img(3:row,:)-img(1:row-2,:))/2;otherwise,disp('Direction is ...
Surface Plot Thesurffunction is used to create a 3-D surface plot. surf(z) Surface Plot (with Shading) Thesurflfunction creates a surface plot with colormap-based lighting. For smoother color transitions, use a colormap with linear intensity variation such aspink. ...
