Struct gramschmidt::Reorthogonalized

pub struct Reorthogonalized { /* fields omitted */ }

A reorthogonalized Gram Schmidt factorization, also known as CGS2 in the literature. See Giraud et al. for a definition. It performs two successive classical Gram Schmidt procedures, which has a higher performance than modified Gram Schmidt while providing a similar numerical stability.

Use this struct via the GramSchmidt trait.
