Computes the QR decomposition of a matrix.
qr2(x, tol = 0.0000001)
A list of two matrices: Q and R.
A matrix whose QR decomposition is to be computed.
The tolerance for detecting linear dependencies in the columns of x.
x
Calls the function base::qr() and returns less compact but more understandable output.
base::qr()
hilbert <- function(n) { i <- 1:n; 1/outer(i-1,i,"+") } h5 <- hilbert(5); qr2(h5)
