Class Slags2

      org.netlib.lapack.Slags2

    public class Slags2

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
     *  =======
     *
     *  SLAGS2 computes 2-by-2 orthogonal matrices U, V and Q, such
     *  that if ( UPPER ) then
     *
     *            U'*A*Q = U'*( A1 A2 )*Q = ( x  0  )
     *                        ( 0  A3 )     ( x  x  )
     *  and
     *            V'*B*Q = V'*( B1 B2 )*Q = ( x  0  )
     *                        ( 0  B3 )     ( x  x  )
     *
     *  or if ( .NOT.UPPER ) then
     *
     *            U'*A*Q = U'*( A1 0  )*Q = ( x  x  )
     *                        ( A2 A3 )     ( 0  x  )
     *  and
     *            V'*B*Q = V'*( B1 0  )*Q = ( x  x  )
     *                        ( B2 B3 )     ( 0  x  )
     *
     *  The rows of the transformed A and B are parallel, where
     *
     *    U = (  CSU  SNU ), V = (  CSV SNV ), Q = (  CSQ   SNQ )
     *        ( -SNU  CSU )      ( -SNV CSV )      ( -SNQ   CSQ )
     *
     *  Z' denotes the transpose of Z.
     *
     *
     *  Arguments
     *  =========
     *
     *  UPPER   (input) LOGICAL
     *          = .TRUE.: the input matrices A and B are upper triangular.
     *          = .FALSE.: the input matrices A and B are lower triangular.
     *
     *  A1      (input) REAL
     *  A2      (input) REAL
     *  A3      (input) REAL
     *          On entry, A1, A2 and A3 are elements of the input 2-by-2
     *          upper (lower) triangular matrix A.
     *
     *  B1      (input) REAL
     *  B2      (input) REAL
     *  B3      (input) REAL
     *          On entry, B1, B2 and B3 are elements of the input 2-by-2
     *          upper (lower) triangular matrix B.
     *
     *  CSU     (output) REAL
     *  SNU     (output) REAL
     *          The desired orthogonal matrix U.
     *
     *  CSV     (output) REAL
     *  SNV     (output) REAL
     *          The desired orthogonal matrix V.
     *
     *  CSQ     (output) REAL
     *  SNQ     (output) REAL
     *          The desired orthogonal matrix Q.
