Haar Condition


A set of vectors in Euclidean n-space is said to satisfy the Haar condition if every set of n vectors is linearly independent (Cheney 1999). Expressed otherwise, each selection of n vectors from such a set is a basis for n-space. A system of functions satisfying the Haar condition is sometimes termed a Tchebycheff system (Cheney 1999).
