Matlab 如何检查是否可以将文件写入目录？

尝试寻找可能有用但运气不佳的函数。我最好的解决方法是尝试使用fopen在目录中创建一个虚拟文件，如果它返回-1，那么我知道我无法创建文件，并且我不会执行其余代码。如果我成功地创建了该文件，我将删除它并继续使用其余代码

这似乎是一种相当不雅观的方法，我宁愿有一行代码告诉我在给定目录中没有写权限。有没有办法做到这一点

您可以创建一个文件夹：

mkdir('folderName')

然后使用movefile将文件复制到该文件夹中：

[status,message,messageid]  = movefile('myfunction.m','oldfunction.m');

状态为逻辑1表示成功，逻辑0表示错误

您还可以获得如下文件夹/文件的权限：

fileattrib('C:\my_MATLAB_files\doc')
ans = 

            Name: 'C:\my_MATLAB_files\doc'
         archive: 0
          system: 0
          hidden: 0
       directory: 1
        UserRead: 1
       UserWrite: 1
     UserExecute: 1
       GroupRead: NaN
      GroupWrite: NaN
    GroupExecute: NaN
       OtherRead: NaN
      OtherWrite: NaN
    OtherExecute: NaN

[S,M] = fileattrib('Directory');
M.UserWrite

ans = 
    1

所以你可以这样做：

fileattrib('C:\my_MATLAB_files\doc')
ans = 

            Name: 'C:\my_MATLAB_files\doc'
         archive: 0
          system: 0
          hidden: 0
       directory: 1
        UserRead: 1
       UserWrite: 1
     UserExecute: 1
       GroupRead: NaN
      GroupWrite: NaN
    GroupExecute: NaN
       OtherRead: NaN
      OtherWrite: NaN
    OtherExecute: NaN

[S,M] = fileattrib('Directory');
M.UserWrite

ans = 
    1
