vectorise a row number search

Hi,

I have a matrix of integer values and a coulm of decimal values, as follows

A = [2 3 7 6; 4 6 4 6; 5 1 3 3]; % a mXn matrix
B = (-0.7, -0.3. -0.1, 0, 0.1, 0.3, 0.7)' ; % a column of bX1 decimal values

Could you help me vectorise (speedup) the following operation of find AA, which is a matrix of decimal values of B.

for i=1:m
        for j=1:n
            AA(i,j) = B(A(i,j),1);
        end
end

Thank you for your help.
