I wish to append my elem to the end of an array A.
What should I do?

- 1This is so duplicated that I don't know where to begin. Do you have a more specific question because I'm sure that you must have searched first.horchler– horchler2014-01-19 02:18:55 +00:00Commented Jan 19, 2014 at 2:18

Use the following
A = [A elem] % for row array or
A = [A; elem] % for col array Edit: Another simpler way is (as @BenVoigt suggested) to use end keyword
A(end+1) = elem; which works for both row and column vectors.

Do I need to declare it first? like
A = {}

@FarticlePilter No, you don't.

a = [1 2 3]; a = [A 4];herohuyongtao
a = [1 2 3]; a = [a 4];

Hi, I was trying to add elements to the end of array inside a loop, but for some reason it won't work. cols = []; for iu = 1:length(id_unique) [~,col] = find(faces(:,:)== iu); cols(end+1) = col; end Do you see a problem in here?
Another way is
A(end+1) = elem; which works for both row and column vectors.

Of course, you have to compute "end" first. Good point though.

@herohuyongtao: No,
end is the MATLAB keyword.
