%   DESCRIPTION:
%     'succ' is called
%
%         successor = succ(a)
%
%     and computes the successor of a given
%     interval matrix a.
%     The successor is defined as
%     succ := min {diam(y) | y > a}.
%
%     The operations on the datatype interval
%     are based on BIAS by Olaf Knueppel.
