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

**LA_HESVX** computes the solution to a linear system of
equations , where is a complex Hermitian
matrix and and are rectangular matrices or vectors.

**LA_SYSVX** and **LA_HESVX** can also optionally estimate the
condition number of and compute error bounds.
