/*  Purpose */
/*  ======= */

/*  CPFTRI computes the inverse of a complex Hermitian positive definite */
/*  matrix A using the Cholesky factorization A = U**H*U or A = L*L**H */
/*  computed by CPFTRF. */

/*  Arguments */
/*  ========= */

/*  TRANSR    (input) CHARACTER */
/*          = 'N':  The Normal TRANSR of RFP A is stored; */
/*          = 'C':  The Conjugate-transpose TRANSR of RFP A is stored. */

/*  UPLO    (input) CHARACTER */
/*          = 'U':  Upper triangle of A is stored; */
/*          = 'L':  Lower triangle of A is stored. */

/*  N       (input) INTEGER */
/*          The order of the matrix A.  N >= 0. */

/*  A       (input/output) COMPLEX array, dimension ( N*(N+1)/2 ); */
/*          On entry, the Hermitian matrix A in RFP format. RFP format is */
/*          described by TRANSR, UPLO, and N as follows: If TRANSR = 'N' */
/*          then RFP A is (0:N,0:k-1) when N is even; k=N/2. RFP A is */
/*          (0:N-1,0:k) when N is odd; k=N/2. IF TRANSR = 'C' then RFP is */
/*          the Conjugate-transpose of RFP A as defined when */
/*          TRANSR = 'N'. The contents of RFP A are defined by UPLO as */
/*          follows: If UPLO = 'U' the RFP A contains the nt elements of */
/*          upper packed A. If UPLO = 'L' the RFP A contains the elements */
/*          of lower packed A. The LDA of RFP A is (N+1)/2 when TRANSR = */
/*          'C'. When TRANSR is 'N' the LDA is N+1 when N is even and N */
/*          is odd. See the Note below for more details. */

/*          On exit, the Hermitian inverse of the original matrix, in the */
/*          same storage format. */

/*  INFO    (output) INTEGER */
/*          = 0:  successful exit */
/*          < 0:  if INFO = -i, the i-th argument had an illegal value */
/*          > 0:  if INFO = i, the (i,i) element of the factor U or L is */
/*                zero, and the inverse could not be computed. */

/*  Note: */
/*  ===== */

/*  We first consider Standard Packed Format when N is even. */
/*  We give an example where N = 6. */
