Abstract

Abstrak. Suatu matriks A = (a
) berukuran n n dikatakan nonpositif total (negatif
total) jika setiap minornya nonpositif (negatif). Pada artikel ini, dipelajari sifat dari
matriks nonpositif total dan kasus karakterisasi dari matriks nonpositif total nonsingular
A dengan a
11
ij
< 0 dalam bentuk faktorisasi LDU dimana L(U) adalah matriks segitiga
bawah (atas) unit dan D adalah matriks diagonal.
