How can I get an upright mu in math with latex interpreter?

I want to display where mu is upright and not italic. Matlab renders the mu always in italic but I need it upright as my university requires it this way. Is there any way to do this?

[John Petersen]

So italic i is okay, but not mu? How can the university require non-italics on a math term? Never heard of that before.

If it does not need to be latex interpreter then possibly using 'i̅/μA' with interpreter tex or none would work ? That is

i U+0305 / U+03BC A

Hi Philipp Rehlaender,

It seems, there is no straight-forward way to do that in matlab figures. Nonetheless, there are work-arounds that help to create a look-like:

Despite that you can create your text freely using unicode. Helpful is the wikipedia list of Unicode blocks. Signs above characters are known as Combining Diacritical Marks.

Writing your requested line in standard text font as axes label:

textbar = sprintf('\x0304'); % is not the bar but looks better, for correct "bar" use \x0305
textmu  = sprintf('\x03BC');

fh = figure;
ah = axes(fh);
ah.XLabel.String = sprintf('%s/%s%s',append('i',textbar),textmu,'A');

Edit: That is, what Walter suggested in short.

Kind regards,

Robert

Dear Robert U,

thank you for your good support. Your solution makes my text look very much alike. However, I still have one problem when exporting the figure. In the exported PDF File, my text font changes from Times to what looks like Arial. In the Matlab figure, everything looks fine though...

Appearently, there is a problem in exporting directly to pdf which has been reported already 2016, and probably earlier: https://de.mathworks.com/matlabcentral/answers/301427-why-does-matlab-2016a-automatically-change-font-size-of-my-figure-when-i-save-it-as-pdf

You can try to use another save-command: https://de.mathworks.com/matlabcentral/answers/58943-how-can-i-keep-the-fontsize-on-colorbar-when-saving-as-jpeg-tiff-etc

A work-around is to use a vector graphics format, and convert to PDF later on: http://www.hargaden.com/enda/blog/different-fonts-for-matlab-plots-exported-to-pdf/

Kind regards,

Note: Using unicode will unfortunately not work for Interpreter Latex .
