I want to add legend to the right of the colorbar, and I tried doing so using the legend function, but it is not shown... using the text function places it outside the printanle area. Can anyone help ? Thanks,,, matlab legend Share Improve this question Follow asked Oct 15, 2012...
Ahh. So your color image is still RGB. It's not being shown as indexed into the colormap which is why it's not showing up. In order for it to show up with the colorbar, you will have to convert it to an indexed image using I...
在MATLAB中,使用imagesc函数显示图像时,默认情况下图像数据的原点(即(1,1)点)位于左上角。如果你希望在y方向上反转图像,可以通过反转图像数据矩阵的行来实现。以下是如何做到这一点的详细步骤: 理解imagesc函数的基本用法: imagesc函数用于显示矩阵数据,其中矩阵的每个元素值对应图像中的一个像素值。颜色映射(colormap...

1.二维热力图(heatmap):通过使用colormap函数,将二维数据映射到颜色空间,并通过imagesc函数将映射后的图像显示出来。 ```matlab data = rand(10, 10); %生成一个10x10的随机矩阵 imagesc(data); %显示热力图 colormap jet; %使用jet colormap colorbar; %显示颜色图例 ``` 2. 3D曲面图:可以使用surf函数...
