This is a follow-up question to How to append an element to an array in MATLAB?How to append an element to an array in MATLAB? That question addressed how to append an element to an array. Two approaches are discussed there:

A = [A elem] % for a row array A = [A; elem] % for a column array

and

A(end+1) = elem;

The second approach has the obvious advantage of being compatible with both row and column arrays.

However, this question is: which of the two approaches is fastest? My intuition tells me that the second one is, but I'd like some evidence for or against that. Any idea?
