Upright \mu with latex interpreter

How do I get an upright \mu with the latex interpreter as figure label? I tried different things which were suggested in other posts like using \mathrm or the char(181). Nothing worked! Especially using char(181) is not supported with the latex interpreter. However, I need the latex interpreter in order to format the entire label text correctly.

ylabel('$\hat{x}$ in $\mathrm{\mu}$m', 'Interpreter', 'latex');

Do you have any ideas, how to solve this issue?

The short answer is that MATLAB cannot do this.

Please give feedback to TMW at the bottom of the page here:

The only working (but rather fiddly) alternative that I have seen is this:

Unfortunately, MATLAB's current LaTeX interpreters do not support upright Greek letters. Due to frequent requests for a non-italized \mu, we are currently considering adding \upmu support in a future MATLAB release. While our rendering infrastructure doesn't allow adding full LaTeX packages like upgreek, we are exploring the possibility of implementing individual commands. So as Stephen mentioned, readers are encouraged to contact MathWorks Technical Support to express their interest in support for specific non-italicized Greek letters.

Note that \mathrm is only intended to apply to uppercase and lowercase letters but not symbols. So inside of \mathrm, Greek letters like \mu are still expected to be italic.

You can consider the workarounds for the TeX interpreter that have been discussed on MATLAB Answers:
