Thread Subject: Find the number of different in Matlab

I wonder if there a Matlab function that returns the number of different element in 2 same length arrays Matlab?

For example
a = [0, 1 , 2, 3, 4]
b = [0, 0, 0 , 0, 4]
compareNumberDifferent(a,b) = 3 as {2 , 3, 4 element in 2 arrays are different}

numel(setdiff(a,b))

sum(a ~= b)

Thank You Very Much for Your Helps
