To whom it may concern, sorry for asking something of such simple nature, but I can not figure it out on my own. Is GMM able to calculate the orthonormal basis for the range of a matrix? Something like "orth()" in Matlab ( http://www.mathworks.de/help/matlab/ref/orth.html ). I found the gmm_modified_gram_schmidt header, which seems to be what I want but since there is no documentation on the functions I find myself unable to understand how they are meant to be applied. For example, given a matrix M: gmm::row_matrix<gmm::wsvector<double>> M1; M1.resize(4,4); // Insert some data And now I would like to get a matrix containg the orthonormal base of M1. Thank you for your time, P. Berger |
