Use heamap().

Demo:

data = diag(randi(20,1,20)+40);
heatmap(data)
xlabel('predicted')
ylabel('actual')
%Create colormap that looks like the image in the question
cm = [linspace(1,0,100)', linspace(1,0,100)', linspace(.875,1,100)']; %from [1 1 .875] to [0 0 1]
colormap(cm)
% or just use
% colormap(flipud(colormap('parula')))

Glad I could help. I just updated the answer to include a colormap that approximates the colormapping in the image in your question.

I see. sprintfc() is an undocumented built-in matlab function. Apparently you have another file with the same name and that file is a script.

That line is just creating fake labels, anyway. You probably already have your own labels. In any case, you can replace that line with this.

labels = strsplit(sprintf('%c ','a':'t')); 
labels(end) = []

Dear Adam, how to plot figure like this, two values (347 and 14.6% or can use words insteads of number in the sheet). Thank you so much.

@ Tran Hoa, this thread may become a bit difficult to follow when there are several "answers" posted that are not answer, but discussion. Please use the "comment" section under a particular answer or under the question if you'd like to continue discussion. The "answer" section is for proposing answer to the question stated at the top of the page.

You can't edit the text displayed in a heatmap. Here's a link to some alternatives:
