Compare values within a matrix

I am comparing two matrices of different dimensions (A and B). I want to find values in B that are within 1 number unit to A. Is there anyway I can do this? B is a smaller matrix than A.
Thanks

if you mean to find all numbers that are equal to each other when disregarding the numbers behind the comma than you can use something like this
A_r = round(A);
B_r = round(B);
C = intersect(A_r,B_r);

A = [31 16 8; 38 4 10];
B = [30 15 7; 34 5 14];
nA = size(A, 1);
match = false(1, nA)
for iA = 1:nA
D = abs(bsxfun(@minus, A(iA, :), B)) <= 1.0;
match(iA) = any(all(D, 2));
end
