Class Dspcon

      org.netlib.lapack.Dspcon

    public class Dspcon

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
     *  =======
     *
     *  DSPCON estimates the reciprocal of the condition number (in the
     *  1-norm) of a real symmetric packed matrix A using the factorization
     *  A = U*D*U**T or A = L*D*L**T computed by DSPTRF.
     *
     *  An estimate is obtained for norm(inv(A)), and the reciprocal of the
     *  condition number is computed as RCOND = 1 / (ANORM * norm(inv(A))).
     *
     *  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.
     *
     *  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.
     *
     *  ANORM   (input) DOUBLE PRECISION
     *          The 1-norm of the original matrix A.
     *
     *  RCOND   (output) DOUBLE PRECISION
     *          The reciprocal of the condition number of the matrix A,
     *          computed as RCOND = 1/(ANORM * AINVNM), where AINVNM is an
     *          estimate of the 1-norm of inv(A) computed in this routine.
     *
     *  WORK    (workspace) DOUBLE PRECISION array, dimension (2*N)
     *
     *  IWORK    (workspace) INTEGER array, dimension (N)
     *
     *  INFO    (output) INTEGER
     *          = 0:  successful exit
     *          < 0:  if INFO = -i, the i-th argument had an illegal value
     *
