Linear Least Squares (LLS) Problems: LAPACK Driver Routines
This topic describes LAPACK driver routines used for solving linear least squares problems. Table "Driver Routines for Solving LLS Problems" lists all such routines for the FORTRAN 77 interface. The corresponding routine names in the Fortran 95 interface are without the first symbol.
Routine Name |
Operation performed |
---|---|
Uses QR or LQ factorization to solve a overdetermined or underdetermined linear system with full rank matrix. |
|
Computes the minimum-norm solution to a linear least squares problem using a complete orthogonal factorization of A. |
|
Computes the minimum-norm solution to a linear least squares problem using the singular value decomposition of A. |
|
Computes the minimum-norm solution to a linear least squares problem using the singular value decomposition of A and a divide and conquer method. |
|
Solves overdetermined or underdetermined real linear systems involving a matrix or its transpose using a tall skinny QR or short wide LQ factorization. |
