Class Slae2

    java.lang.Object
      org.netlib.lapack.Slae2

    public class Slae2

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
     *  =======
     *
     *  SLAE2  computes the eigenvalues of a 2-by-2 symmetric matrix
     *     [  A   B  ]
     *     [  B   C  ].
     *  On return, RT1 is the eigenvalue of larger absolute value, and RT2
     *  is the eigenvalue of smaller absolute value.
     *
     *  Arguments
     *  =========
     *
     *  A       (input) REAL
     *          The (1,1) element of the 2-by-2 matrix.
     *
     *  B       (input) REAL
     *          The (1,2) and (2,1) elements of the 2-by-2 matrix.
     *
     *  C       (input) REAL
     *          The (2,2) element of the 2-by-2 matrix.
     *
     *  RT1     (output) REAL
     *          The eigenvalue of larger absolute value.
     *
     *  RT2     (output) REAL
     *          The eigenvalue of smaller absolute value.
     *
     *  Further Details
     *  ===============
     *
     *  RT1 is accurate to a few ulps barring over/underflow.
     *
     *  RT2 may be inaccurate if there is massive cancellation in the
     *  determinant A*C-B*B; higher precision or correctly rounded or
     *  correctly truncated arithmetic would be needed to compute RT2
     *  accurately in all cases.
     *
     *  Overflow is possible only if RT1 is within a factor of 5 of overflow.
     *  Underflow is harmless if the input data is 0 or exceeds
     *     underflow_threshold / macheps.
     *
     * =====================================================================
