Beschreibung

Die Funktion isLinearlyIndependent testet, ob Vektoren linear unabhägig sind. Die Funktion erwartet eine Liste von Vektoren und gibt einen Boolean zurück.

Syntax

 isLinearlyIndependent(List liste)

Parameter

• vektoren - List von Vektor, die auf lineare Unabhängigkeit geprüft werden sollen

Return Value

• Gibt einen Boolean zurück

Beispiele

 isLinearlyIndependent(list(vector(1,1), vector(1,2)))    --> returns true
