How to highlight a certain pixel when using the imagesc command?
显示 更早的评论
I have a small 3-by-7 matrix which I have plotted using the imagesc() function to get a small map of an area of data.
Is there any way to be able to highlight a certain pixel with a red outline or something similar?
Many thanks!

You can use something similar to below code.
imagesc(floor(rand(3,7)*10))
hold on
plot([2.5,2.5,3.5,3.5,2.5],[3.5,2.5,2.5,3.5,3.5],'r','linewidth',3)
hold off
