b4m Version 1.0.2 (first official release) Revision .004
This Release is based on Beta-Version 1.0.2.003

  -- Still problems with the overloaded methods

        subsasgn.m and subsref.m,

     because Matlab 5.2 does not call them inside
     other M-Files in the class directory, only from
     other directories in the search path of Matlab
     or from the command window display.

  -- Some small errors have been corrected and
     some more experimental files are omitted.

  -- b4m now computes least squares and minimal
     norm solutions (A\b).

  -- The global variables are now called
     b4m_DouBLe, b4m_INTerval and b4m_NaTiVe.

  -- The matrix right divide (mrdivide, '/')
     now can be invoked with second non-scalar
     argument.

                                          Jens Zemke 16.10.1998

  -- The routines interval, diag, transpose,
     ctranspose and sum now achieve higher speed.

  -- The routines isinf, isfinite and isnan are now
     available (completing isempty).

  -- The routines tril and triu are now implemented
     for interval matrices.
