Module linxal::factorization::qr [−] [src]

Compute the QR-factorization of a rectangular matrix.

An (m x n) rectangular matrix A is factored into the produce Q * R, such that

  • The columns of Q are orthonormal, and the span of the first k columns of Q contains the subspaces spanned by the first k columns of A, for all 1 <= k <= n.

  • R is an upper triangular or upper-trapezoidal matrix.

Structs

QRFactors

Representation of the components Q, R of the factorization of matrix A.

Enums

QRError

Error for QR-based computations.

Traits

QR

Trait defined on scalars to support QR-factorization.
