How to print NaN for unexist value instead of error message

Is there any way to print NaN instead of error message due to the two matrix are not valid.. For example, in this simple codes

clc, clear all
x = [1,2,3,4,5]; 
y = [3,4,5,6,7];
for i = 1: length(x)
    out = x(i)+y(i+1);
    fprintf('%.0f \t', out)
end

On other hand, please do not recommended me to do like this,

clc, clear all
x = [1,2,3,4,5]; 
y = [3,4,5,6,7];
for i = 1: length(x)-1
    out = x(i)+y(i+1);
    fprintf('%.0f \t', out)
end
fprintf('NaN \t')

---- result should be

5 7 9 11 NaN

I'm looking for trick which is fancy and more professional to fill unexcist variable by printing word like "NaN"

Try this:

x = [1,2,3,4,5];
y = [3,4,5,6,7];
for i = 1: length(x)
    try
        out = x(i)+y(i+1);
    catch
        out = NaN;
    end
    fprintf('%.0f \t', out)
end
