I have to compute the hamming distance between two matrices.

a=[240*7]; b=[240*7]; dist=hamming (a,b);

but this code shows error.

what i do? I need the solution.

hamming is not for hamming distance I guess. What is the type of input you want to compute the hamming distance.

Hamming distance is usually calculated between character array or binary array. For binary array it is very simple and straight forward.

For binary array sum of absolute difference can give you hamming distance.

For example.

a = [1 0 0 1];
b = [1 1 1 1];
h_d = sum(abs(a-b));

What if i have to find the hamming distance between two rows of a binary array?
