%   DESCRIPTION:
%     'pred' is called
%
%         predecessor = pred(a)
%
%     and computes the predecessor of a given
%     real matrix a.
%     The predecessor for real argument
%     is defined as
%     pred := max {b | b < a}.
%
%     The operations on the datatype interval
%     are based on BIAS by Olaf Knueppel.
