How can I raise a power in gui edit text

Hello everyone

As i asked on the title I want to raise a power in edit text. like P1

I tried with latex but it didn't work for me

Thank you

There is not a lot of support for rich text formatting in Matlab. I don't really know any editable field where you can use it.

In several static text places you can use rich text formatting (e.g. by using the LaTeX interpreter for text, title, etc), but outside of those I don't know of a method that would allow this.

A possible loophole is with the special unicode characters:

%superscript 0123456789
char([8304 185 178 179 8308 8309 8310 8311 8312 8313])

(note that char values beyond 255 can have a limited support depending on release and OS)

The unicode characters Rik mentions are the only way to do it with uicontrol style edit, unless you are willing to go in at the Java level.

In particular tex and latex are not supported for uicontrol style edit. Also HTML character entities and CSS are not supported for uicontrol style edit. HTML character entities are supported for some of the other uicontrol styles.

Is this what you're looking for?

% Put P1 squared with subscript 5
title('P1^2_5', 'Interpreter', 'tex', 'FontSize', 20);

"gui edit text", so I don't think this is what is being asked about.

yea I am also looking for the same I want to input for my equation in edit text

as : 3.33 *10^-12

but its giving me NanH

[Walter Roberson]

If you use a text area then you could risk using num2str() . Or you could do text processing:

S = '3.33 *10^-12'

S = '3.33 *10^-12'

num = str2double(regexprep(S, '\s*\*\s*10\^(-?\d+)', 'E$1'))

num = 3.3300e-12

It can be difficult trying to parse user input. For example did they use spaces, etc.? Did they use an exponent? Etc. Here's a start:

S = '3.33 *10^-12'
% S = '3.34' % See if it works with no exponent
% Remove any spaces.
S = strrep(S, ' ', '')
index1 = strfind(S, '*10^') - 1;
% Find the first number
if isempty(index1)
	n1 = str2double(S) % No exponent, just take the whole number.
else
	n1 = str2double(S(1:index1))
end
% Find the exponent - the second number.
index2 = strfind(S, '^') + 1;
if ~isempty(index2)
	n2 = int32(str2double(S(index2:end)))
	caption = sprintf('%.2f * 10^{%d}', n1, n2)
else
	% No *10 to a power, it's just a number.
	caption = sprintf('%.2f', n1)
end
title(caption, 'Interpreter', 'tex', 'FontSize', 20);

Here's a post of all the available text edit options in app designer. In summary, it is possible to use an interpreter in axis titles, text objects in an axis, colorbar label strings, and legend titles.

All other components do not yet support interpreters (as of 2018a).
