.nf
 CSYT03 computes the residual for a complex symmetric matrix times
 its inverse:
    norm( I - A*AINV ) / ( N * norm(A) * norm(AINV) * EPS )
 where EPS is the machine epsilon\&.

\fIUPLO\fP 
.PP
.nf
          UPLO is CHARACTER*1
          Specifies whether the upper or lower triangular part of the
          complex symmetric matrix A is stored:
          = 'U':  Upper triangular
          = 'L':  Lower triangular

          N is INTEGER
          The number of rows and columns of the matrix A\&.  N >= 0\&.

.nf
          A is COMPLEX array, dimension (LDA,N)
          The original complex symmetric matrix A\&.

\fILDA\fP

.nf
          LDA is INTEGER
          The leading dimension of the array A\&.  LDA >= max(1,N)

\fIAINV\fP 
.PP
.nf
          AINV is COMPLEX array, dimension (LDAINV,N)
          On entry, the inverse of the matrix A, stored as a symmetric
          matrix in the same format as A\&.
          In this version, AINV is expanded into a full matrix and
          multiplied by A, so the opposing triangle of AINV will be
          changed; i\&.e\&., if the upper triangular part of AINV is
          stored, the lower triangular part will be used as work space\&.
