x=[1 3 9 6 4 2 6 8 3 6];
y=[4 -2 6 8 8 3 7 2 1 1];
cityblockvalue = sum((abs(x - y)));
cityblockvalue= 32

b is not a vector. It depends what the relationship between a and b is.
Assuming that a is a row vector and applies in whole to each row of b in the same way, then the distance for each row is:
x = [1 2 3];
y = [4 5 6; % i made this 4x3 so that it's easy to see the orientation
7 8 9;
10 11 12;
13 14 15];
D = pdist2(x,y,'cityblock').'
D = sum((abs(x - y)),2) % works R2016b+
