DOUBLE PRECISION AP( * )

*
-* Purpose
-* =======
-*
-* DTPTRI computes the inverse of a real upper or lower triangular
-* matrix A stored in packed format.
-*
-* Arguments
-* =========
-*
-* UPLO (input) CHARACTER*1
-* = 'U': A is upper triangular;
-* = 'L': A is lower triangular.
-*
-* DIAG (input) CHARACTER*1
-* = 'N': A is non-unit triangular;
-* = 'U': A is unit triangular.
-*
-* N (input) INTEGER
-* The order of the matrix A. N >= 0.
-*
-* AP (input/output) DOUBLE PRECISION array, dimension (N*(N+1)/2)
-* On entry, the upper or lower triangular matrix A, stored
-* 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)*((2*n-j)/2) = A(i,j) for j<=i<=n.
-* See below for further details.
-* On exit, the (triangular) inverse of the original matrix, in
-* the same packed storage format.
-*
-* INFO (output) INTEGER
-* = 0: successful exit
-* < 0: if INFO = -i, the i-th argument had an illegal value
-* > 0: if INFO = i, A(i,i) is exactly zero. The triangular
-* matrix is singular and its inverse can not be computed.
-*
-* Further Details
-* ===============
-*
-* A triangular matrix A can be transferred to packed storage using one
-* of the following program segments:
-*
-* UPLO = 'U': UPLO = 'L':
-*
-* JC = 1 JC = 1
-* DO 2 J = 1, N DO 2 J = 1, N
-* DO 1 I = 1, J DO 1 I = J, N
-* AP(JC+I-1) = A(I,J) AP(JC+I-J) = A(I,J)
-* 1 CONTINUE 1 CONTINUE
-* JC = JC + J JC = JC + N - J + 1
-* 2 CONTINUE 2 CONTINUE
