Calculate Hamming distance between two strings of binary digits in Matlab

Question

I have two lines with the same length, containing 1 and 0. Each line has a length of 128 bits, and I want to calculate the Hamming distance between them. How can I do this?

eg. a = '1000001' and b = '1110001' → dist = Hamming (a, b);

Answer 1

Use pdist with the hamming parameter.

Answer 2

 dist = sum(a ~= b);
