%X Meijerink and Van der Vorst proposed an incomplete-Cholesky conjugate gradient me-thod. In this paper, for the matrix derived from an elliptic problem, the accurate estimate ofthe condition number after preconditioning with the method in 1] is given.And we proposean incomplete-Cholesky conjugate gradient method with a parameter. Numerical results showour method has improved the one in 1].
