A= [1 2 2 1 1 1 2 2 2 2 2 1 1 2 2 0 2 2 0 0 0 1  2 2 2 1 0 1 ];
ArrayOut1=zeros(size(A));
ArrayOut2=ArrayOut1;
idx1=union(strfind(A,[1 2]),strfind(A,[0 2]));
idx2=union(strfind(A,[2 1]),strfind(A,[2 0]))+1;
v=all(A([idx1' idx2']),2);
ArrayOut1(cell2mat(arrayfun(@(x) idx1(x)+1:idx2(x)-1,find(v)','un',0)))=2;
ArrayOut2(cell2mat(arrayfun(@(x) idx1(x)+1:idx2(x)-1,find(~v)','un',0)))=2;

Or in case A start (or/and) ends with 2

A= [2 2 1 1 1 2 2 2 2 2 1 1 2 2 0 2 2 0 0 0 1 2 2 2 1 0 1 2 ];
ArrayOut1=zeros(size(A));
ArrayOut2=ArrayOut1;
A=[0 A 0];
idx1=union(strfind(A,[1 2]),strfind(A,[0 2]));
idx2=union(strfind(A,[2 1]),strfind(A,[2 0]))+1;
v=all(A([idx1' idx2']),2);
ArrayOut1(cell2mat(arrayfun(@(x) idx1(x):idx2(x)-2,find(v)','un',0)))=2
ArrayOut2(cell2mat(arrayfun(@(x) idx1(x):idx2(x)-2,find(~v)','un',0)))=2
