I mean..... I tried to delete a file and matlab told me that the file dont exist, ok. But later I tried to check for file existence and matlab told me that exist. At windows explorer the file don`t exist.

Some idea about this issue? My matlab 7.10.0.499 64-bit win7

This may happen when the file you are trying to delete is in the matlab path not in the current directory. Try providing the full path for the file in the delete command. Also it is better to use

delete('filename')

instead of

delete filename
