write superscript in string

6 views (last 30 days)
Hello all,
I'm trying to show my R squared as a title but i wan 2 to be as a superscript not just R2. Here's my inputs:
R2 = 0.75;
t = sprintf('R^2 = %0.2f',R2);
title(t)
this gives me
t = 'R2 = 0.75'
but what I want is R superscript 2.

It could be the interpreter. Does this work for you?
R2 = 0.75;
t = sprintf('R^2 = %0.2f',R2);
title(t,'interpreter','tex')
Also, it might be relevant to know what this returns for you:
get(groot,'defaultTextInterpreter')
