matlab 2014之后就不再支持matlabpool函数,而改用parpool函数.
但是有些文档上依然使用的matlabpool函数,在此记录一下matlabpool函数和parpool用法之间的关系:

function varargout = matlabpool(varargin)

     varargout={};
     arg1=varargin{1};

     switch arg1

       case 'open'

         parpool(varargin{2:end});

       case 'close'

         delete(gcp('nocreate'));

       case  'size'

         p = gcp('nocreate'); % If no pool, do not create new one.

        if isempty(p)
            poolsize = 0;
        else
            poolsize = p.NumWorkers;
        end

        varargout={poolsize};

    otherwise %number of workers

         if ~isnumeric(arg1)
           arg1=num2str(arg1);
         end

         parpool(arg1);

end
