confusion matrix with string greek letters like alpha and beta

6 views (last 30 days)
I have a string matrix with is supposed to have greek letters.
Example: My matrix contains the abbreviation: B-Glc, but I want it to appear as β-Glc in the matrix and on the axis of the confusion matrix.
I have tried '/beta' but it did not work.
Thnak you

If you use the actual greek letters, that should work (as long as the function supports all implemented characters):
text(1,1,char(945:969))
axis([0 5 0 2])

Unfortunately, confusionchart does not have any control over interpreter. However if you insert unicode characters into the class labels, the characters will be drawn (if present in the font.)

I solved this issue (only a turnaround)
% alpha is the greek letter
alpha = cellstr(char(945));
% Label1 is the true label and I am appending an optional string to alpha.
% Label(1,1) will contain /alpha-Glu in greek
Label1(1,1)= strcat(string(alpha), '-GLu');
Label2(1,1)=strcat(string(alpha), '-MM');
% Apply confusionchart to Label1 and Label2
confusionchart(categorical(Label),categorical(Label2));
the class labels on the axes as greek letters rather than normal letters

You are right, no need to cellstr() and string(). Thank you
