使用‘plotmatrix’命令,绘制未经美化的散点矩阵图。 % S - 散点图的图形线条对象 % AX - 每个子坐标区的坐标区对象 % BigAx - 容纳子坐标区的主坐标区的坐标区对象 % H - 直方图的直方图对象 % HAx - 不可见的直方图坐标区的坐标区对象 [S,AX,BigAx,H,HAx] = plotmatrix(X); hTitle = title(...
plotmatrix(X,Y)plotmatrix(X)plotmatrix(___,LineSpec)[S,AX,BigAx,H,HAx]=plotmatrix(___) plotmatrix(X,Y) 创建一个子坐标区矩阵,包含了由 X 的各列相对 Y 的各列数据组成的散点图。如果 X 是 p×n 且 Y 是 p×m,则 plotmatrix 生成一个 n×m 子坐标区矩阵。 除了用 X 对应列中数据的...
A colormap is a matrix of values that define the colors for graphics objects such as surface, image, and patch objects. MATLAB draws the objects by mapping data values to colors in the colormap. Dozens of different colormap color maps are preset in Matlab, as shown in Fig:今天的分享就到...
well... i tried to use both answers and the realiza same thing: figure divided in color by the numbers in matrix. instead i want to know how to have a picture(jpg for intend) that is my matrix if A=[1 2 3;4 5 6;7 8 9]; i want to realize a way to picture a matrix with...
CreateXas a matrix of random data andYas a matrix of integer values. Then, create a scatter plot matrix of the columns ofXagainst the columns ofY. X = randn(50,3); Y = reshape(1:150,50,3); plotmatrix(X,Y) The subplot in the ith row, jth column of the figure is a scatter pl...
colormap gray; %%% Make it a grayscale plot colorbar; %%% Show how the image intensities map onto the colormap axis('image'); %%% Make the proportions correct title('An initial attempt at showing the sagittal slice'); 结果: 2.3 将上面大脑矢状面 图像旋转90度,以正常方式显示 ...
在MATLAB中,读取图像的过程相对简单。使用imread函数可以轻松加载图像。例如,如果您有一个名为"test.jpg"的图像文件,且该文件位于E:\My Documents\Image文件夹中,那么您可以使用以下代码行来读取它:A = imread('E:\My Documents\Image\test.jpg');这里,A代表读取到的图像矩阵。如果图像文件不在 ...
folder using the expression hgsave(gcf, 'Image3D.fig', '-v7.3'); i wish to import the image again to my work space as M*N*O MATRIX.i tryied import to work space but i got 5 variables named children,handle,special,type,properties.i like to impoort it as 3D matr...
第一步:先把txt文件复制到MATLAB的目录,或者在MATLAB中将路径指向txt文件所在路径。第二步:右键存有数据的txt文件,选择Import Data第三步:Import Data之后就能看到txt里的数据被妥善安放好位置了,然后在Range右边的列表中选择Matrix,再点击绿色的对勾√导入数据:第四步:导入完数据后,在work ...
If you specify Y, then gplotmatrix creates a q-by-p matrix of scatter plots using the p columns of X and the q columns of Y. Data Types: single | double | datetime | duration Y— Input data numeric matrix | datetime array | duration array Input data, specified as an n-by-q nume...
