Class DSPTRS

    java.lang.Object
      org.netlib.lapack.DSPTRS

    public class DSPTRS

extends java.lang.Object

    DSPTRS is a simplified interface to the JLAPACK routine dsptrs.
    This interface converts Java-style 2D row-major arrays into
    the 1D column-major linearized arrays expected by the lower
    level JLAPACK routines.  Using this interface also allows you
    to omit offset and leading dimension arguments.  However, because
    of these conversions, these routines will be slower than the low
    level ones.  Following is the description from the original Fortran
    source.  Contact seymour@cs.utk.edu with any questions.

     *  Purpose
     *  =======
     *
     *  DSPTRS solves a system of linear equations A*X = B with a real
     *  symmetric matrix A stored in packed format using the factorization
     *  A = U*D*U**T or A = L*D*L**T computed by DSPTRF.
     *
     *  Arguments
     *  =========
     *
     *  UPLO    (input) CHARACTER*1
     *          Specifies whether the details of the factorization are stored
     *          as an upper or lower triangular matrix.
     *          = 'U':  Upper triangular, form is A = U*D*U**T;
     *          = 'L':  Lower triangular, form is A = L*D*L**T.
     *
     *  N       (input) INTEGER
     *          The order of the 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.
     *
     *  AP      (input) DOUBLE PRECISION array, dimension (N*(N+1)/2)
     *          The block diagonal matrix D and the multipliers used to
     *          obtain the factor U or L as computed by DSPTRF, stored as a
     *          packed triangular matrix.
     *
     *  IPIV    (input) INTEGER array, dimension (N)
     *          Details of the interchanges and the block structure of D
     *          as determined by DSPTRF.
     *
     *  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
     *
