【Abstract】 The paper offers a definition of the conditional eigenfunction of the random variable quantity X on condition that the random variable quantity Y=y. And an attempt is made to discuss the relation ship between the eigenfunction of x and conditional eigenfuction, and also discuss some properties of conditional eigenfunction.更多还原
