SGELS Example
For a detailed description
and reference information on this function, please visit:
The routine solves overdetermined or underdetermined real linear systems involving a
rectangular matrix
A
, or its transpose, using a
QR
or LQ
factorization of A
. The
routine assumes that A
has full rank.Several right-hand side vectors
b
and solution
vectors x
can be handled in a single call; they
are stored as the columns of the right-hand side matrix B
and the solution matrix X
.Fortran-77 Interface
