MATLAB-Direct access of structure fields returned by a function call is not allowed 的解决方法~

今天在MATLAB的命令行窗口直接输入MATLAB路径下名字为“I_005_xianxing.m”的M文件时出现警告，提示如下
Warning: Direct access of structure fields returned by a function call (e.g.,call to I_005_xianxing) is not allowed. See <a href="matlab: helpview([docroot '/techdoc/rn/rn.map'],'cannot_dot_index_function_outputs')">MATLAB 7.10 Release Notes, "Subscripting Into Function Return Values"</a> for details. 

??? Attempt to reference field of non-structure array.

解决方法：在命令行输入的时候把m的后缀去掉就没这个警告了~

原因分析：把后缀.m加上系统会认为你在调用M文件中的函数，然而实际上你就是在运行这个脚本~
