Eigen_range: Range of a matrix
Description
Range (column-space, image, span) of a real or complex matrix.
Usage
Eigen_range(M, method = "QR")
Arguments
M
a matrix, real or complex
method
one of "LU", "QR", or "COD"; the
"LU" method is faster
Value
A basis of the range of M. With method = "LU", the
basis is not orthonormal, while it is with method = "QR" and
method = "COD".
