摘    要：For a random matrix of size $N$ as an additive deformation of the complex Ginibre ensemble under a deterministic matrix $X_0$ with a finite rank, independent of $N$, different statistical behaviours are observed in subcritical, critical and supercritical regimes, both in eigenvalue statistics(via 1-point correlation function) and eigenvector statistics(via the mean self overlap function). Further, a relevant phase transition phenomenon is observed.
