Function Documentation

void mbl_mod_gram_schmidt	(	const vnl_matrix< double > &	v,
		vnl_matrix< double > &	e
	)

Orthogonalise a basis using modified Gram-Schmidt.

Transform basis {vk} to orthonormal basis {ek} with k in range 1..N for j = 1 to N ej = vj for k = 1 to j-1 ej = ej - <ej,ek>ek //NB Classical GS has vj in inner product end ej = ej/|ej| end Convert input basis {v} to orthonormal basis {e}. Each basis vector is a column of v, and likewise the orthonormal bases are returned as columns of e
