I would like to call something like
xlabel( \'Time (μs)\' );
But that just shows up with a question mark on the plot. Is there anyway t
For your specific example, you can get the display you want using TeX\LaTeX formatting:
xlabel('Time ({\mu}s)');
For the more general case of displaying Unicode characters, if you know the code for your character you can convert the decimal value for the code to a character using the function char and build a string like so:
xlabel(['Time (' char(181) 's)']); % Same results as above
