NAME
ZTPTTR  copies a triangular matrix A from standard packed format (TP) to standard full format (TR)
SYNOPSIS
 SUBROUTINE ZTPTTR(

UPLO, N, AP, A, LDA, INFO )

CHARACTER
UPLO

INTEGER
INFO, N, LDA

COMPLEX*16
A( LDA, * ), AP( * )
PURPOSE
ZTPTTR copies a triangular matrix A from standard packed format (TP)
to standard full format (TR).
ARGUMENTS
 UPLO (input) CHARACTER

= aqUaq: A is upper triangular.
= aqLaq: A is lower triangular.
 N (input) INTEGER

The order of the matrix A. N >= 0.
 AP (input) COMPLEX*16 array, dimension ( N*(N+1)/2 ),

On entry, the upper or lower triangular matrix A, packed
columnwise in a linear array. The jth column of A is stored
in the array AP as follows:
if UPLO = aqUaq, AP(i + (j1)*j/2) = A(i,j) for 1<=i<=j;
if UPLO = aqLaq, AP(i + (j1)*(2nj)/2) = A(i,j) for j<=i<=n.
 A (output) COMPLEX*16 array, dimension ( LDA, N )

On exit, the triangular matrix A. If UPLO = aqUaq, the leading
NbyN 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 = aqLaq, the
leading NbyN 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 (input) INTEGER

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

= 0: successful exit
< 0: if INFO = i, the ith argument had an illegal value
