**LA_PBSVX** computes the solution to a linear system of
equations , where has band form and is
real symmetric or complex Hermitian and, in either case,
positive definite,
and where and are rectangular matrices or vectors.

**LA_PBSVX** can also optionally equilibrate the system if
is poorly scaled, estimate the condition number of (the equilibrated) ,
and compute error bounds.
