Filtering data in matrices

AA=Df{1,1};
AAA=AA;
for i=1:length(AA)
    if AA(i) <1 || AA(i)>2
    AAA(i)=[];
    end
end

I am trying to filter data that is between 2 values into a new matrix. Whenever I run this code I get the error

Matrix index is out of range for deletion.

Error in Analyze (line 279)

AAA(i)=[];

Answer 1

AA(AA<1|AA>2) = []

Is there a way to leave it empty so that the matrix is the same size?
