basis {lmreg} | R Documentation |
Computes an orthonormal basis of the column space of a given matrix.
basis(M, tol=sqrt(.Machine$double.eps))
M |
Matrix for which basis of the column space is needed. |
tol |
A relative tolerance to determine rank through qr decomposition |
Returns a semi-orthogonal matrix with columns forming an orthonormal basis of the column space of M.
