How can I add normal text as well as Latex symbols on a figure axis?

1 view (last 30 days)
I wanted to implement some latex symbols into my axis, but I'm stuck on how to add normal text to the caption.
Here is what i wanted to do:
str = '$$ Absolute x-acceleration \ddot{x_{A}} [m/s²]$$';
ylabel(str, 'Interpreter','latex');
However, putting normal text between these $ symbols, results in an error. How can I combine the text with the xA symbol (x dubble dotted and A in subscript)
Thanks in advance!

This is something that I don't fully understand actually, and I'd love to get some explanation from TMW. Some times (maybe on older versions), I had to set the interpreter afterwards. On my 2017b this works:
>> ylabel( '$\mbox{Absolute x-acceleration}~\ddot{x}_{A} [m/s^2]$', 'Interpreter', 'latex' ) ;
but I remember having had to do it in two operations:
>> h_yl = ylabel( '$\mbox{Absolute x-acceleration}~\ddot{x}_{A} [m/s^2]$' ) ;
set( h_yl, 'Interpreter', 'latex' ) ;
If you are in a situation where you leave it enough time generate a warning, you can just start by disabling that warning.
NOTE : in your expression, what was not valild was the superscript ².
