Over a commutative domain of elementary divisors, each matrix is a product of invertible matrices and a certain diagonal matrix, which are called, respectively, transforming matrices and a canonical diagonal form. We establish necessary and sufficient conditions when all divisors of the matrix that have a canonical diagonal form given beforehand are described using only transforming matrices.
