LaTex with 2 strings separated by a num2str

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),'\%'];
