Thread Subject: Open a new folder

Thanks for your attention:

My question is:

1, How to open a new foloder under current/or some
particular drectory by matlab and save some file in it?
The folder's name is defined using
foldername = sprintf--- based on current
parameters/variables.

2. I can open a file at current directory using
fopen('xxx.txt', 'wt');
But it fails when I tries to open a file in a folder "A"
under current directory using
fopen('\A\xxx.txt', 'wt');
How to accomplish this.

-I know it can be done by making the directory full using
fopen('C:\A\xxx.txt', 'wt'); while this make it difficult
to us when you move the file into a new folder with
different directory.

Thanks a lot.

See help mkdir

mkdir(foldername);

fopen('A\xxx.txt', 'wt');

As others have mentioned, use MKDIR.

Use the FULLFILE function to combine the current directory name (which you
can obtain using the PWD function) and the subdirectory name. If your code
needs to be cross-platform, you may also want to use the FILESEP function to
construct your subdirectory name.
