\fBPurpose:\fP
.RS 4

.PP
.nf
 DLATTP generates a triangular test matrix in packed storage\&.
 IMAT and UPLO uniquely specify the properties of the test
 matrix, which is returned in the array AP\&.

\fIIMAT\fP 
.PP
.nf
          IMAT is INTEGER
          An integer key describing which matrix to generate for this
          path\&.
.fi

\fIUPLO\fP 
.PP
.nf
          UPLO is CHARACTER*1
          Specifies whether the matrix A will be upper or lower
          triangular\&.

.nf
          ISEED is INTEGER array, dimension (4)

.nf
          A is DOUBLE PRECISION array, dimension (N*(N+1)/2)
          The upper or lower triangular matrix A, packed columnwise in
          a linear array\&.  The j-th column of A is stored in the array
          AP as follows:
          if UPLO = 'U', AP((j-1)*j/2 + i) = A(i,j) for 1<=i<=j;
          if UPLO = 'L',
             AP((j-1)*(n-j) + j*(j+1)/2 + i-j) = A(i,j) for j<=i<=n\&.
