**LA_GESVX** computes the solution to a real or complex linear
system of equations of the form , or ,
where is a square matrix and and are
rectangular matrices or vectors.

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