Arguments

A
(input/output) REAL or COMPLEX array, shape $(:,:)$ with $size({\bf A},1) = m$ and $size({\bf A},2) = n$.
On entry, the matrix $A$.
On exit, the contents of A are destroyed.

B
(input/output) REAL or COMPLEX array, shape $(:,:)$ with $size({\bf B},1) = p$ and $size({\bf B},2) = n$.
On entry, the matrix $B$.
On exit, the contents of B are destroyed.

C
(input/output) REAL or COMPLEX array, shape $(:)$ with $size({\bf C}) = m$.
On entry, the vector $c$.
On exit, the residual sum of squares for the solution is given by the sum of squares of elements $n-p+1$ to $m$.

D
(input/output) REAL or COMPLEX array, shape $(:)$ with $size({\bf D}) = p$.
On entry, The vectors $d$.
On exit, the contents of D are destroyed.

X
(output) REAL or COMPLEX array, shape $(:)$ with $size({\bf X})=n$.
The solution vector $x$.

INFO
Optional (output) INTEGER.

\begin{infoarg}
\item[{$=$\ 0:}] successful exit.
\item[{$<$\ 0:}] if {\bf INFO} $= -i$, the $i^{th}$\ argument had an illegal
value.
\end{infoarg}
If ${\bf INFO}$ is not present and an error occurs, then the program is terminated with an error message.
