bdQR: QR Decomposition

In BigDataStatMeth: Statistical Methods and Algorithms for Big Data

QR Decomposition

Description

This function compute QR decomposition (also called a QR factorization) of a matrix A into a product A = QR of an orthogonal matrix Q and an upper triangular matrix R.

Usage

bdQR(X, thin = NULL)

Arguments

X	a real square matrix
thin	boolean thin, if thin = true returns Q thin decomposition else returns Q full decomposition, default thin = false

Value

List with orthogonal matrix Q and upper triangular matrix R
