public class Dpttrs

extends Object

Following is the description from the original
Fortran source.  For each array argument, the Java
version will include an integer offset parameter, so
the arguments may not match the description exactly.
Contact seymour@cs.utk.edu with any questions.

 *     ..
 *
 *  Purpose
 *  =======
 *
 *  DPTTRS solves a system of linear equations A * X = B with a
 *  symmetric positive definite tridiagonal matrix A using the
 *  factorization A = L*D*L**T or A = U**T*D*U computed by DPTTRF.
 *  (The two forms are equivalent if A is real.)
 *
 *  Arguments
 *  =========
 *
 *  N       (input) INTEGER
 *          The order of the tridiagonal matrix A.  N >= 0.
 *
 *  NRHS    (input) INTEGER
 *          The number of right hand sides, i.e., the number of columns
 *          of the matrix B.  NRHS >= 0.
 *
 *  D       (input) DOUBLE PRECISION array, dimension (N)
 *          The n diagonal elements of the diagonal matrix D from the
 *          factorization computed by DPTTRF.
 *
 *  E       (input) DOUBLE PRECISION array, dimension (N-1)
 *          The (n-1) off-diagonal elements of the unit bidiagonal factor
 *          U or L from the factorization computed by DPTTRF.
 *
 *  B       (input/output) DOUBLE PRECISION array, dimension (LDB,NRHS)
 *          On entry, the right hand side matrix B.
 *          On exit, the solution matrix X.
 *
 *  LDB     (input) INTEGER
 *          The leading dimension of the array B.  LDB >= max(1,N).
 *
 *  INFO    (output) INTEGER
 *          = 0:  successful exit
 *          < 0:  if INFO = -i, the i-th argument had an illegal value
