Purpose

LA_SPSVX computes the solution to a linear system of equations $AX = B$, where $A$ is a real or complex symmetric matrix stored in packed format and $X$ and $B$ are rectangular matrices or vectors.
LA_HPSVX computes the solution to a linear system of equations $AX = B$, where $A$ is a complex Hermitian matrix stored in packed format and $X$ and $B$ are rectangular matrices or vectors.
LA_SPSVX and LA_HPSVX can also optionally estimate the condition number of $A$ and compute error bounds.
