[討論] catch me的me是什麼東西?
網路上下載的到parfor的進度條
我在網路上下載到ParforProgressStarter2這個進度條
裡面範例:
N = 1000000;
try % Initialization
ppm = ParforProgressStarter2('test', N, 0.1);
catch me % make sure "ParforProgressStarter2" didn't get moved to a different
directory
if strcmp(me.message, 'Undefined function or method
''ParforProgressStarter2'' for input arguments of type ''char''.')
error('ParforProgressStarter2 not in path.');
else
% this should NEVER EVER happen.
msg{1} = 'Unknown error while initializing "ParforProgressStarter2":';
msg{2} = me.message;
print_error_red(msg);
% backup solution so that we can still continue.
ppm.increment = nan(1, nbr_files);
end
end
parfor i = 1 : N
N;
ppm.increment(i);
end
try % use try / catch here, since delete(struct) will raise an error.
delete(ppm);
catch me %ok<NASGU>
end
大致上看得懂他想表達什麼，因為有英文字說明
但是它裡面那個me是什麼? 中間有個要把me的訊息(me.message)跟另一段訊息比對
想知道me到底是什麼，才能知道me.message是什麼@@
求高手指點!!!
