A note on completely positive matrices of order 5

摘要：

A matrix A is called completely positive(CP) if A=BB for some nonnegative matrix B, and doubly nonnegative(DNN) if A is both entrywise nonnegative and positive semidefinite. We present here some necessary and sufficient condition for a DNN matrix of order 5 to be CP.
