Hi,
I have to compute the L1 distance (Manhattan distance) between matrices. Is there a fast way that avoid to use for loop? I have found this code for euclidean distance
if true
aa=sum(a.*a,2); bb=sum(b.*b,2); ab=a*b';
d = sqrt(abs(repmat(aa,[1 size(bb,1)]) + repmat(bb',[size(aa,1) 1]) - 2*ab));
end
Thank you

Jan, put your cursor on the text entry box without anything selected, and press the {} Code button...
