Hi, I have 20 files with '.dat' and '.mat' extension in one folder. And I have problem with deleting files with extension '.mat'. I have written this in order to delete mat files

delete(any(size(dir(['DataPath/*.mat' ]),1)))

after deleting one '.mat ' it showing error

Error using delete
Argument must contain a string.
Error in myfile(line 81)
              delete(any(size(dir(['DataPath/*.mat' ]),1)))

Can any one please tell me how to solve this problem

在 MATLAB Online 中打开

delete(any(size(dir(['DataPath/*.mat' ]),1)))

I would be extremely surprised (stunned) if that worked. The any function returns a logical value, so what you're running is:

delete(true) % or
delete(false)

If you want to delete ALL the files with the .mat extension in that subdirectory, see the first example on the delete documentation page. If you want to delete some of the files, explain in more detail (in words, not code) what you want to do and we may be able to help you do that.
