isemptycell.m

马尔可夫过程是一类重要的随机过程,它的原始模型马尔可夫链,由俄国数学家Α.Α.马尔可夫于1907年提出。本程序是对隐马尔可夫模型的一个完整的建模。

function E = isemptycell(C)
% ISEMPTYCELL Apply the isempty function to each element of a cell array
% E = isemptycell(C)
%
% This is equivalent to E = cellfun('isempty', C),
% where cellfun is a function built-in to matlab version 5.3 or newer.

if 0 % all(version('-release') >= 12)
  E = cellfun('isempty', C);
else
  E = zeros(size(C));
  for i=1:prod(size(C))
    E(i) = isempty(C{i});
  end
  E = logical(E);
end
