Givens orthogonalisation

Orthogonalization using Givens' method.

givens_orth(X, nullspace = FALSE)

`X`	a numeric matrix with ncol(X) <= nrow(X)
`nullspace`	logical: do you want an orthogonal basis for the null space?

A list with components Q, R, as normally defined, and if nullspace is TRUE a further component N giving the basis for the requested null space of X

set.seed(1234)
X <- matrix(rnorm(7*6), 7)
givens_orth(X, nullspace = TRUE)
