Class Dpbtrs

    java.lang.Object
      org.netlib.lapack.Dpbtrs

    public class Dpbtrs

extends java.lang.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.

     *  Purpose
     *  =======
     *
     *  DPBTRS solves a system of linear equations A*X = B with a symmetric
     *  positive definite band matrix A using the Cholesky factorization
     *  A = U**T*U or A = L*L**T computed by DPBTRF.
     *
     *  Arguments
     *  =========
     *
     *  UPLO    (input) CHARACTER*1
     *          = 'U':  Upper triangular factor stored in AB;
     *          = 'L':  Lower triangular factor stored in AB.
     *
     *  N       (input) INTEGER
     *          The order of the matrix A.  N >= 0.
     *
     *  KD      (input) INTEGER
     *          The number of superdiagonals of the matrix A if UPLO = 'U',
     *          or the number of subdiagonals if UPLO = 'L'.  KD >= 0.
     *
     *  NRHS    (input) INTEGER
     *          The number of right hand sides, i.e., the number of columns
     *          of the matrix B.  NRHS >= 0.
     *
     *  AB      (input) DOUBLE PRECISION array, dimension (LDAB,N)
     *          The triangular factor U or L from the Cholesky factorization

     *          A = U**T*U or A = L*L**T of the band matrix A, stored in the

     *          first KD+1 rows of the array.  The j-th column of U or L is
     *          stored in the j-th column of the array AB as follows:
     *          if UPLO ='U', AB(kd+1+i-j,j) = U(i,j) for max(1,j-kd)<=i<=j;

     *          if UPLO ='L', AB(1+i-j,j)    = L(i,j) for j<=i<=min(n,j+kd).

     *
     *  LDAB    (input) INTEGER
     *          The leading dimension of the array AB.  LDAB >= KD+1.
     *
     *  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
     *
