man wngs (Fonctions bibliothèques) - Gramm-Schmidt orthogonalization

NAME

wn_gramm_schmidt - Gramm-Schmidt orthogonalization

#include <wn/wnmat.h>

void wn_gramm_schmidt(int code, double **mat, int len_i, int len_j)

wn_gramm_schmidt performs an in-place run on mat. mat[i] are vectors which span the space; sweep is from i=0 to i=len_i-1.

Gramm-Schmidt requires

WORST and AVERAGE CASE:

time = len_i^2*len_j

stack memory = 1

dynamic memory = 0

where the matrix to be processed is a len_i*len_j matrix.

code == WN_SUCCESS for success.

code == WN_SINGULAR for singular matrix.
