谁能解释解释这个错误可能的原因吗

烟火之夏

Error in AP_cal_dectionary (line 6)
fprintf('Building Dictionary using Training Data AP 聚类\n\n');

Output argument "dictionarysize" (and maybe others) not assigned during call to
"E:\MATLAB\bin\Matlib_WordBag\词包实验\AP_cal_dectionary.m>AP_cal_dectionary".

Error in main (line 35)
[dictionarysize]=AP_cal_dectionary(pg_opts, dictionary_opts);

百年孤独

函数AP_cal_dectionary需要返回dictionarysize的值，但是你的函数里面并没有定义这个值。
