/* Purpose */
/* ======= */
/* ZGTTS2 solves one of the systems of equations */
/* A * X = B, A**T * X = B, or A**H * X = B, */
/* with a tridiagonal matrix A using the LU factorization computed */
/* by ZGTTRF. */
/* Arguments */
/* ========= */
/* ITRANS (input) INTEGER */
/* Specifies the form of the system of equations. */
/* = 0: A * X = B (No transpose) */
/* = 1: A**T * X = B (Transpose) */
/* = 2: A**H * X = B (Conjugate transpose) */
/* N (input) INTEGER */
/* The order of the matrix A. */
/* NRHS (input) INTEGER */
/* The number of right hand sides, i.e., the number of columns */
/* of the matrix B. NRHS >= 0. */
/* DL (input) COMPLEX*16 array, dimension (N-1) */
/* The (n-1) multipliers that define the matrix L from the */
/* LU factorization of A. */
/* D (input) COMPLEX*16 array, dimension (N) */
/* The n diagonal elements of the upper triangular matrix U from */
/* the LU factorization of A. */
/* DU (input) COMPLEX*16 array, dimension (N-1) */
/* The (n-1) elements of the first super-diagonal of U. */
/* DU2 (input) COMPLEX*16 array, dimension (N-2) */
/* The (n-2) elements of the second super-diagonal of U. */
/* IPIV (input) INTEGER array, dimension (N) */
/* The pivot indices; for 1 <= i <= n, row i of the matrix was */
/* interchanged with row IPIV(i). IPIV(i) will always be either */
/* i or i+1; IPIV(i) = i indicates a row interchange was not */
/* required. */
/* B (input/output) COMPLEX*16 array, dimension (LDB,NRHS) */
/* On entry, the matrix of right hand side vectors B. */
/* On exit, B is overwritten by the solution vectors X. */
/* LDB (input) INTEGER */
/* The leading dimension of the array B. LDB >= max(1,N). */
