Is it possible to display text with subscripts using fprintf in R2016a ? I would like to change Nmax.
fprintf('\nMaximum value of N is Nmax = 2\n');
Maximum value of N is Nmax = 2

In MATLAB R2016a, "fprintf" does not support displaying text with subscripts directly because it outputs plain text, and subscripts are a feature of formatted text (like LaTeX or rich text). However, there are workarounds to display subscripts depending on the output medium:
  • If you need to display subscripts in a figure, you can use text or annotation with TeX or LaTeX formatting, which supports subscripts:
figure;
text(0.1, 0.5, 'Maximum value of N is N_{max} = 2', 'Interpreter', 'tex');
fprintf('y\x2098')
yₘ
I hope this helps!

I meant that even this does not work:
fprintf('y\x2098')
yₘ

It doesn't work.
It does in LiveScript or other rich text environments:
myfprintf('Maximum value of N is N_{max} = 2')
myfprintf('Minimum value of N is N_{min} = 1')
function myfprintf(str)
hF=figure;hAx=gca;
imagesc(nan(10,500),'AlphaData',0); axis image; axis off;
Ht=text(250,5,str,'Interpreter','tex','Horiz','right');
hF.InnerPosition(end)=hAx.OuterPosition(end)*30;
end

Not all letters have unicode subscripts but m, a, and x do, so you're in luck.
x = 2;
fprintf(1,'Maximum value of N is N%c%c%c=%.0f\n',[8344 8336 8339 x]);
Maximum value of N is Nₘₐₓ=2
More info
  • webnots page that lists unicodes for super- and subscript letters
  • subscript generator - to get the numeric unicode values, copy the results in matlab and run double('<results>')

Ah, that would be a matter of setting the command window font to one that supports unicode.
