You need to push on @AoA a reference to @vector: 
my @vector = (4.3125, 0.4375);
push @AoA, \@vector;
@vector = (4.375, 0.375);
push @AoA, \@vector;

That way is buggy, though, as the redefinition of @vector will clobber the first pushed array element. This is explained under COMMON MISTAKES in perldsc, "taking a reference to the same memory location repeatedly".

So both lines above should instead use a square bracket reference. 

push @AoA, [ @vector ];
