MATLAB: Highlight cells in heatmap

You can do so by creating a custom colormap. The code below shows a simple implementation.

xvalues = 1:5;
yvalues = 1:5;
cdata = randi(20,[5,5]); % range of values in cells < 20
cmap = [repmat([1 0 0],5,1)
    repmat([1 1 1],5,1) % highlight all cells with values from 5-10 with white
    repmat([0 0 0],10,1)]; % highlight all cells > 10 with black
heatmap(1:5,1:5,randi(20,[5 5]),'Colormap',cmap);
