We present an efficient inexact implicitly restarted Arnoldi algorithm to find a few eigenpairs of large unitary matrices. The approximating Krylov spaces are built using short-term recurrences derived from Gragg's isometric Arnoldi process. The implicit restarts are done by the Krylov-Schur methodo
