matlab 批量读入文件夹中的指定文件类型 ，目录级数不限

比较久以前写的一个批处理文件。测试可用。

可以读入文件中的任意类型文件<理论上是这样。O(∩_∩)O~现在主要是图片格式和txt，还有csv这几种格式，具体的大家可以再加>。不限文件夹中子文件夹的个数和层数。

ps一个，文件中原本打算设计可以批量写成文件。但是这部分想来似乎不是很有用。所以就没有做。

如果大家要对读入的数据进行处理，可以在%load function处添加你要的function即可。其输入参数使用Output_Data。

 1 function [ Output_data ] = File_Batch_Processing( Input_path  , File_type  )
 2 %bat_file has agrments as follow: 
 3 %1. the folder where you want to read or write. agrments *Input_path
 4 %2. the type you want to , generally, read or write. *Operate_mothed
 5 %3. the file type you want to , currently , is txt,jpg,bmp,dat , and so
 6 %on.*File-type
 7 %4. the perfix name of the writing file.*File_type
 8 %Read Mode
