A = ceil(A);

if 0 < A(i,j) && A(i,j) <= 1
Please note, that if depending on the data it is not required to check 1 < A(i,j) again, when A(i, j) <= 1 has been excluded before (and no A < 0 cases appear).
A(A>0 & A<=1) = 1;
A(A>1 & <=2) = 2;
Of course if you'd like to do this continuously (constantly rounding values, not just between [0 1] and [1 2]) then use Walter Roberson's method for speed and ease of implementation.
