SYNOPSIS

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

Function/Subroutine Documentation

   subroutine ctpttr (characterUPLO, integerN, complex, dimension( * )AP, complex, dimension(
       lda, * )A, integerLDA, integerINFO)
       CTPTTR copies a triangular matrix from the standard packed format (TP) to the standard
       full format (TR).

       Purpose:

            CTPTTR 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 COMPLEX 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 COMPLEX 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
