Bayes Net Toolbox MATLAB的结构学习包

Question

我正在审核this MATLAB code，它有一些示例，我正在执行test_bnpc_asia.m，但是收到错误，如何纠正？ （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 =

Warning: Direct access of structure fields returned by a function call (e.g.,
 call to test_bnpc_asia) is not allowed. See MATLAB 7.10 Release Notes, "Subscripting Into Function Return Values" for details.

Answer 1

你应该输入

test_bnpc_asia

而不是

test_bnpc_asia.m

自动添加文件扩展名。如果你添加它，MATLAB认为函数test_bnpc_asia返回一个结构，你想访问该结构中包含的字段“m”。
