Hello, I am having problem when I want to change the title of the variables to be seen on the each plot.
for ii=1:length(ending_cell)
HOR=1:options_.irf;
var={'yhat', 'URhat', 'chat', 'what'};
figure
for jj=1:length(var)
for jj=1:length(var)
subplot(2,2,jj)
eval(['irf1.' var{1,jj},ending_cell{1,ii}]);
eval(['irf2.' var{1,jj},ending_cell{1,ii}]);
hold on
plot(HOR,[eval(['irf1.' var{1,jj},ending_cell{1,ii}])],'-k',HOR,[eval(['irf2.' var{1,jj},ending_cell{1,ii}])],'--r','LineWidth',2) ;
axis tight
legend('No labor friction(JQ)','Labor f');
%title(['Output','Unemployment','Consumption','Wage'])
title([var{1,jj}] )
end
end
end
Any idea how I can chnage it ?
Thank you

Can you possibly let us know what exactly you want this to output? This will make it easier for people to help.

Do NOT use eval for accessing fields of a structure, simply use dynamic fieldnames instead:
https://www.mathworks.com/help/matlab/matlab_prog/generate-field-names-from-variables.html
And of course do NOT access variable names dynamically:
https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval
Your code would be a lot simpler, easier to debug,and more efficient if you avoided eval.

Than you for the reply.
Well, I just simply want to change the name of variables yhat, URhat, chat, what to be Output, Unemployment, Consumption, wage. They need to be appear as the title of the plots I get.
There is no problem for code to work I just wanted to make some changes.
Thank you

If you have a problem making changes that often implies there is a problem with the code! Easy to use code is also easy to change and understand. I can't understand what on earth your code is doing through all the evals in order to make a suggestion that would, in all likelihood, be trivial with simpler code.

Output=yhat;
Unemployment=URhat;
Consumption=chat;
wage=what;
You can always also use:
clear vars yhat URhat chat what
if you want to remove the duplicates with the old naming.
I may be missing something, so if this isn't what you want then let me know and I'll see what I can do to help.
