我正在查看此MATLAB代码 (http://www.mathworks.com/matlabcentral/fileexchange/13562-structure-learning-package-for-bayes-net-toolbox) ，并且其中有一些示例，我正在执行test_bnpc_asia.m，但出现错误，该如何更正？ （我有MATLAB R2010B）
执行：
>> test_bnpc_asia.m ================== phase I : Execution time : 0.12480 ================== phase II : Execution time : 0.01560 ================== phase III : Thinning - separateA Thinning - separateB Thinning - orient_edges Infering directions 0 boucles Execution time : 0.10920 score_Phase_3 = -6.0994e+003 Report genered in : ans = C:\Program Files\MATLAB\R2010b\BNT_SLP\examples Warning: Direct access of structure fields returned by a function call (eg, call to test_bnpc_asia) is not allowed. See MATLAB 7.10 Release Notes, "Subscripting Into Function Return Values" for details. ??? Attempt to reference field of non-structure array.
回答：
您应该输入
test_bnpc_asia 代替
test_bnpc_asia.m 文件扩展名将自动添加。如果添加它，MATLAB会认为函数test_bnpc_asia返回一个结构，并且您想访问该结构中包含的字段“ m”。
