f2 = figure;

The ‘a1’ variable is a ‘handle’ to the axes object.
In (I hope) more understandable terms, it shows all the properties of the axes of ‘f2’. This is useful if you want to find out what they are, and more usefully, to change them after the figure was plotted. This is particularly important if you want to change the tick positions, tick labels, or other characteristics of the axes object.
To see all the properties, add this line after the ‘a’ assignment:
a1_detail = get(a1)

Pure speculation here. Were you actually intending to return the parent object of f2? In that case you want
get(f2,'Parent')
or
f2.Parent

Probably not. axes('Parent', f2) is the proper syntax for creating a new axes whose parent is f2 .
