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

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