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]

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

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

but, i want aNewElement to be, n+1

like [ 1 4 2 8 8+1]

newX = [X, X(end)+1];
