if I have a matrix [1,2] and I want to add a 3rd element [3] to make [1,2,3]
And what is this simple manipulation called? 2 hours of searching has got me nowhere.
Kind regards

@Robert: The operation is called "concatenation". Such questions are exhaustively explained in the "Getting Started" chapter of the documentation. While it is strongly recommended to read them, because Matlab is a very powerful language, the forum is not the right place to learn the very basics. Thanks.

Sorry for not being able to find it and being thick, Yes this is how your question addresses me. Dyslexia can be very cruel, yet it spawns all of the greatest thinkers of our time. How is this very useful bit of advice going to help someone trying to learn. I suppose you have never had difficulty finding a simple answer before. If you don't like the question just don't answer it! We should be encouraging people not making them too scared to ask for help. Not impressed one iota!

Hint:
x = [ 1, 2 ];
x(end+1) = 3;
or
x = cat( 2, x, 3 );

And:
x = [x, 3]
which is equivalent to:
x = horzcat(x, 3)
