SGELS Example

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
.

C Interface

Please refer to the Matrix Layout section of the C Interface Conventions for the description of Row Major (C default) and Column Major (Fortran default).
