NAME
       dtpttr.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dtpttr (UPLO, N, AP, A, LDA, INFO)
	   DTPTTR copies a triangular matrix from the standard packed format
	   (TP) to the standard full format (TR).

Function/Subroutine Documentation
   subroutine dtpttr (characterUPLO, integerN, double precision, dimension( *
       )AP, double precision, dimension( lda, * )A, integerLDA, integerINFO)
       DTPTTR copies a triangular matrix from the standard packed format (TP)
       to the standard full format (TR).

       Purpose:

	    DTPTTR copies a triangular matrix A from standard packed format (TP)
	    to standard full format (TR).

       Parameters:
	   UPLO

		     UPLO is CHARACTER*1
		     = 'U':  A is upper triangular.
		     = 'L':  A is lower triangular.

	   N

		     N is INTEGER
		     The order of the matrix A. N >= 0.

	   AP

		     AP is DOUBLE PRECISION array, dimension ( N*(N+1)/2 ),
		     On entry, 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(i + (j-1)*j/2) = A(i,j) for 1<=i<=j;
		     if UPLO = 'L', AP(i + (j-1)*(2n-j)/2) = A(i,j) for j<=i<=n.

	   A

		     A is DOUBLE PRECISION array, dimension ( LDA, N )
		     On exit, the triangular matrix A.	If UPLO = 'U', the leading
		     N-by-N upper triangular part of A contains the upper
		     triangular part of the matrix A, and the strictly lower
		     triangular part of A is not referenced.  If UPLO = 'L', the
		     leading N-by-N lower triangular part of A contains the lower
		     triangular part of the matrix A, and the strictly upper
		     triangular part of A is not referenced.

	   LDA

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

	   INFO

		     INFO is INTEGER
		     = 0:  successful exit
		     < 0:  if INFO = -i, the i-th argument had an illegal value
