如何快速检查matlab中脚本的文件目录是否正确？

Question

我有一个脚本，它依赖于位于特定文件夹中的不同文件，这些文件对于无错误运行脚本很重要。为了定义路径位置，我决定使用相应的路径位置名称作为字符串创建许多变量：

file directory var   file directory location            % default entries which
                                                        % only work with my computer
fd_1  =            '\C:\Testrun\pathfinder.xls\';            
fd_2  =            '\C:\Testrun\pathfilter.slx\';
fd_3  =            '\C:\Testrun\splinegenerator.xls\';
fd_4  =            '\C:\Testrun\loftcreator.xls\';
fd_5  =            '\C:\Testrun\surface_to_volume.xls\';
fd_6  =            '\C:\Testrun\stp_creator.xls\';
fd_7  =            '\C:\Testrun\CAD_file.stp\';
fd_8  =            '\C:\Testrun\CAD_support_1.atm\';
fd_9  =            '\C:\Testrun\CAD_support_2.atm\';
fd_10 =            '\C:\Testrun\CAD_support_3.atm\';

这让我可以在我的电脑上使用我的脚本。然而，这是一个非常静态的解决方案，仅适用于一台电脑。因此，我需要对以下动态例程进行编码：

0.) I created a while loop in order to rerun my script with the switch case/expression:

<<<here is the missing code for the file directory check>>>  
%(I wanted to use the "strcmp" command to compare the strings with each other?)

<<<Here is my code with the specific while loop to rerun it>>>


1.) Before I enter this loop need to perform a quick check, if the files are correctly located.
2.) If the file directory cannot be assigned to the specific variables responsible for the file 
    directory name (e.g directory could not be found), a new file directory will be choosen by the 
    user
3.) The newly choosen file directory will be stored with the default file directory in a list
4.) The variable responsible for the file directory changes according to the list index which the 
    user choose from the list of stored file directory names
5.) The selection of the specific list index as well as the changes in the list will be permenantly 
    stored (The changes in the list should be saved and recalled again in the script upon rerunning 
    or exiting/reopening the script)
6.) The list index can be deleted if the user is unsatisfied with the file directory (e.g due the 
    file directory corruption)

是否可以编写这样的代码以及如何构建它？

Answer 1

我想把所有的文件夹和文件放在主程序的同一个路径下，这样就不用说c:\或d:之类的盘符了，只需要提及文件夹名和子文件夹，就可以复制了主文件夹并在另一台计算机上运行您的程序而无需更改任何内容，只需运行主程序即可。
