Find maximum difference between two arrays
显示 更早的评论
I have to arrays of the same size 1x101, how can I find the absolute maximum difference between the arrays?
This is what I tried but it is giving me the incorrect answer:
[m] = max( abs( A(1,101) - B(1,101) ))

Because the code compares a single element i.e. (1,101), not the whole vectors.
Use this -
m = max(abs(A-B.'),[],'all');

No need to compare all the pairs
A = randn(1,101);
B = randn(1,101);
dmaxBruteForce = max(abs(A-B.'),[],'all')
dmaxSmart = max(abs([max(B)-min(A), max(A)-min(B)]))
