On the Precise Number of (0,1)-Matrices in u(R, S)
(0, 1)-matrix, Binary digits, Row and column sum vectors
This paper gives a reduced formula for the precise number of matrices in A(R,S), the class of matrices of zeros and ones with row and column sum vectors R and S, respectively. With the new formula, the computing time is greatly shortened.
