Mit Bandmatrix wird in der numerischen Mathematik eine Matrix bezeichnet, bei der zusätzlich zur Hauptdiagonalen nur eine bestimmte Anzahl von Nebendiagonalen Elemente ungleich null aufweist. Sind nur eine untere und eine obere Nebendiagonale ungleich null, so spricht man von Tridiagonalmatrizen. Diese Matrizen sind damit dünnbesetzte Matrizen mit einer speziellen Struktur. Bandmatrizen entstehen häufig bei der Diskretisierung von Differentialgleichungen. 웹2024년 4월 11일 · Product. Transparent matrices. MPN. TORVM-1-092. Material. Silicone. Country/Region of Manufacture.
