In this paper, a sufficient condition is obtained to ensure the stable recovery (? ?0) or exact recovery (? = 0) of all r-rank matrices X ??sup> m×n from \(b = \mathcal{A}(X) + z\) via nonconvex Schatten p-minimization for any \(\delta _{4r} \in \left[ {\frac{{\sqrt 3 }} {2},1} \right)\). Moreover, we determine the range of parameter p with any given δ\(\delta _{4r} \in \left[ {\frac{{\sqrt 3 }} {2},1} \right)\). In fact, for any given \(\delta _{4r} \in \left[ {\frac{{\sqrt 3 }} {2},1} \right)\), p ?(0, 2(1 ?δ4r)] suffices for the stable recovery or exact recovery of all r-rank matrices.
