By matrix technique,it is shown that the ring of endomorphisms of a projective module P of rank n can be expressed as S=Y T Mm(R) X,where(X,Y) is a m-projective basis couple.文中借助于矩阵计算方法,证明了轶为n的投射R-模P的自同态环可以表示为S=YTMm(R)X,其中(X,Y)为P的一个m-基耦,还证明了P是自由R-模当且仅当Rn*P作为Mn(R)-模是循环模,当且仅当Rn*P≠∪i(Rn*P)Mi,其中Mi取遍S的极大左理想。
