I calculate a vector within a for loop and wish to append all the vectors that I calculate in that loop together. How do I do this efficiently?

The efficient way is not to do that. Use indexing instead. If the vectors are not equal length you can put them in a cell array first and then use this:
out=vertcat(out{:});% or horzcat
