Hi all, I have what I hope to be a simple question. This is the code I am working on now.
errordisplay=[' $\varepsilon_{RTP}=$ ',num2str(rtep),];
text(30,15,errordisplay,'interpreter','latex')
I want to add a percent sign after the conversion of 'rtep'. But when I do this
errordisplay=[' $\varepsilon_{RTP}=$ ',num2str(rtep),'%'];
the conversion of ' $\varepsilon_{RTP}=$ ' goes away and leaves the string as typed.
Any ideas?
Thanks in advance

Try this:
errordisplay=[' $\varepsilon_{RTP}=$ ',num2str(rtep),'\%'];
It seems you need to ‘escape’ the ‘%’.

Use an escape (backslash) for the %
errordisplay=[' $\varepsilon_{RTP}=$ ',num2str(rtep),'\%'];
