      org.netlib.lapack.Slarrc

    public class Slarrc

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
     *  =======
     *
     *  Find the number of eigenvalues of the symmetric tridiagonal matrix T

     *          = 'L':  Compute Sturm count for matrix L D L^T.
     *
     *  N       (input) INTEGER
     *          The order of the matrix. N > 0.

     *  PIVMIN  (input) DOUBLE PRECISION
     *          The minimum pivot in the Sturm sequence for T.
     *
     *  EIGCNT  (output) INTEGER
     *          The number of eigenvalues of the symmetric tridiagonal matrix
     *          that are in the interval (VL,VU]
     *
     *  LCNT    (output) INTEGER
     *  RCNT    (output) INTEGER
