MATLAB: Add n+1 element to a vector

Question

I have a vector of the format:

x = [X1 X2 … Xn]

I want to add an element to the end, X(n+1). How do I do that?

ex: x = [ 1 4 2 8]

newX = [ 1 4 2 8 9]

Answer 1

If your X is a row vector, using newX = [X, aNewElement];

If your X is a column vector, using newX = [X; aNewElement];
