how to find the manhattan distance between 2 matrices of defferent size

how can i find the manhattan distance between two matrices?

e.g the mahattan distance between w and p.

w= [4 5 6; 6 7 8; 9 9.1 9.2;]

p= [1 2 3]

I would assume you mean you want the “manhattan distance”, (otherwise known as the L1 distance,) between p and each separate row of w. If that assumption is correct, do this.

   d = sum(abs(bsxfun(@minus,p,w)),2);

This will give you a 3 x 1 column vector containing the three distances.

Hey Roger,

I have one problem:

I have Matrix of size 3 x 4 and another one is 2 x 4, both matrices are binary, then how to calculate pairwise manhattan distance matrix? Please suggest method in vectorize form.
