Pdist between 2 binary matrices


how can I calculate the hamming distance between two binary matrices?

for example:

A = [ 1 0 1; 1 1 1 ];
B = [ 1 0 0 ; 0 0 1 ];

Thanks so much!


Solution

  • If by Hamming distance you mean an element-wise distance between two matrices you can simply use xor:

    D = xor(A,B);
    

    And the total distance over elements:

    D_total = nnz(D);
