DTLS

 
Solves, by using a total least squares approximation, the overdetermined system
of equations AX=B where both the data matrix A as well as the observation matrix B
are inaccurate. This routine will also solve square and underdetermined systems
by computing the minimum norm solution. (See S. Van Huffel, J. Comp. Appl. Math. 25
(1989) pp. 111-119.).
 
Classes  :  D9a1 . Least squares (L-2) solution of singular, overdetermined or
                 underdetermined systems of linear equations without
                 constraints
            D9a4 . Other solutions of singular, overdetermined or
                 underdetermined systems of linear equations without
                 constraints
