I've calculated area under the curve and saved it under 'a'. I'm using annotation function in MATLAB such that
annotation(figure1,'textbox',[0.643 0.22 0.5 0.1],'String','Area_s_s = ','FitBoxToText','on');
After the Area_s_s I want to display the saved value a and I though that if INSERT = a,'kJm^-3' such that
annotation(figure1,'textbox',[0.643 0.22 0.5 0.1],'String','Area_s_s = ',INSERT,'FitBoxToText','on');
I will be able to call up the saved value a and add the units afterwards but it's not working.
All I basically want to do is add a previously calculated area under the curve on the plot in a function so that I don't have to do it manually since I have quite a few data to go through. I'm new to using textbox function and I am very much open to any suggestions you might have to achieve this in a different way.
Thank you in advance for taking time to read my question.

Replace:
'Area_s_s = '
with
['Area_s_s = ',num2str(a),'kJm^-3']
in the annotation. It's also better if you use sprintf instead of num2str so you can control the number format.
