In this paper we analyze the positive (sign-symmetric) P -matrix completion problem when the pattern of the partial matrix is non-symmetric. We prove that every positive (sign-symmetric) partial P -matrix A has a positive (sign-symmetric) P -matrix completion when the associated graph of the specifi
