• Matrix completion
• Gradient
• Projection
• Feasible sequence
• Convergence

In this paper, a new gradient projection method is proposed, which generates a feasible matrix sequences. The decent property of this method is proved. Based on the decent property, the convergence of the new method is discussed. Moreover, a sufficient and necessary condition for the optimal matrix is obtained. Finally, numerical experiments show the new method is effective in precision.
