I have a matrix A with observations (only two in the example) in the rows and features (five in the example) in the columns. I want to find the number of rows where any element is larger than the target value in vector b.

A = [1,2,3,4,5 ; 5,5,5,5,5]
b = [2,3,4,5,6]

I tried it with this code

length(find(A > b))

But then the answer is 3, since the first row is ok, but in the second row, three elements in A exceed the correpsonding elements in b. However, I just want to have them count as 1 row and not as 3.
