摘要：
A characterization of linear operators preserving directional majorization is given. The result extends a theorem of T. Ando [Linear Algebra Appl. 118 (1989) 163], and the proof also gives the characterization of linear operators preserving multivariate: majorization recently obtained by Beasley and Lee.
