Tilde character underneath a letter in Matlab charts

I am trying to put a tilde underneath a letter in my ylabel on a chart in Matlab. I am using interpreter and latex to do it and i know the way to do it in Latex is \utilde. But Matlab does not seem to recognise this command, it does recognise \tilde, however.

Has anyone tried to put a character underneath a letter in Matlab for chart plots? How can I do this?!

Thanks!

The following code may be able to help you.

ylabel('$\stackrel{a}{\tilde{}}$','Interpreter','latex');

[Olivia Milton-thompson]

Thank you for your response!!

Problem with that is the 'a' appears to be a superscript...

Doesn't stackrel create objects to be put on top of one another? I just need to have a normal sized letter with a tilde underneath.

Thank you!

Is this what are you looking for

ylabel('$\stackrel{a}{\tilde{}}$','Interpreter','latex','FontSize',60);
set(get(gca,'ylabel'),'rotation',0);

No that second one is definitely not what I wanted, I don't want to rotate the axis or make the font bigger haha, just wanted a normal letter with a tilde underneath, not a superscript with a tilde underneath. But...

Your first answer has worked I think, just not in the way I expected it to and I'm not sure why it worked haha. Initially when I used your first code above, it just gave what it shows on the attachment (capture), with the a and tilde as a superscript. But I wanted to have it as a normal a with a tilde underneath, not a superscript.

But then I decided to just try and complete what I wanted to do using your original line of code and for some reason it worked, shown on the attachment (capture2). I needed the tilde underneath the i and it's done it. Does not make much sense to me as to why stackrel worked in this case and didnt keep it as a superscript, but that's fine, it's worked! Thanks!

If you do not need latex then use 'a' followed by U+0330. Unicode can be used for interpreter none or tex

[Olivia Milton-thompson]

Could you be more specific as to how to write this? For example within a ylabel axis. Thanks!

[Walter Roberson]

ylabel(sprintf('aãa\x0330'))

[Olivia Milton-thompson]

That still didn't work, no tilde is appearing underneath the "a" and I can't see how I would be able to put text before the symbol with a tilde in this case. But not to worry, I've manage to botch it with the very first suggested answer

[Walter Roberson]

It works for me on Mac, R2019b. Which release and OS are you using?

Example of incorporating text and variables:

autilde =['a' hex2dec('0330')];
iter = 17;
ylabel( sprintf('%s%s%d', 'experiment #', autilde, iter))

[Olivia Milton-thompson]

Still can't see any tilde, sadly!

Using your code above, I get the picture shown on the attachment.

I'm using Windows, R2019a, so shouldnt be too wildly different to you!
