CGELSS.C

 
Computes the minimum norm least squares solution to an over- or under-determined
system of linear equations A X=B, using the singular value decomposition of A.
(Simple driver.). [C version of LAPACK routine, converted from Fortran by f2c.].
 
Classes  :  D9a1 . Least squares (L-2) solution of singular, overdetermined or
                 underdetermined systems of linear equations without
                 constraints
 
Type     : C subroutine in CLAPACK package.
Access   : Public domain. Portable.
Precision: Single.
Note     : For best results, CLAPACK developers prefer that you download and
           install the entire CLAPACK library on your system. To do this, see the 
           netlib CLAPACK distribution for details.
