\fBPurpose: \fP
.RS 4

.PP
.nf
 ZSPTRS solves a system of linear equations A*X = B with a complex
 symmetric matrix A stored in packed format using the factorization
 A = U*D*U**T or A = L*D*L**T computed by ZSPTRF.

\fIUPLO\fP 
.PP
.nf
          UPLO is CHARACTER*1
          Specifies whether the details of the factorization are stored
          as an upper or lower triangular matrix.
          = 'U':  Upper triangular, form is A = U*D*U**T;
          = 'L':  Lower triangular, form is A = L*D*L**T.
