If I generate an imagen with imagesc for the Covariance matrix of the ovarian cancer data how do I mark the healthy and patient groups in my plot?
load ovariancancer
cov_all = cov(obs');
figure()
imagesc(cov_all)
colormap default
colorbar

DISCLAIMER: These are my own views and in no way depict those of MathWorks.
You can do this by adding the color limit property.
Example:
C = [0 2 4 6; 8 10 12 14; 16 18 20 22];
clims = [cmin cmax];
imagesc(C,clims)
colorbar
Here, any value below cmin will have the color assigned to cmin and any value ablove cmax will have the color assigned to cmax.
For more information on imagesc, here is the documentation page: imagesc
Hope this helps.
