Save folder one above current directory

Let's say I am working in the directory:
/home/username/Matlab/
I want to save (in a script) the directory one above the one I am working in (to use it later in the script), so:
newdir='home/username';
But I am working in different computers, so the 'username' changes, thus I want to do it automatically, such as save "newdir" as "one above the current directory".
Thank you

Folder = cd;
Folder = fullfile(Folder, '..');
save(fullfile(Folder, 'FileName.mat'))

"Is this a problem with the way uigetfile works?"
No, there is no problem with how UIGETFILE works. The UIGETFILE documentation states "To specify a folder name only, make the last character of the defname value either a backslash (\) or a slash (/)."
Once you add the trailing fileseparator it will work as you require and as documented. As an alternative, if you are using FULLFILE it might be easier to add a trailing asterisk like this:
fullfile(..,'..','*')

Zynk - try using pwd with strfind to determine the index of the last occurrence of the slash /. Then just remove it and everything that follows. Something like
mydir = pwd;
idcs = strfind(mydir,'/');
newdir = mydir(1:idcs(end)-1);
Try the above (or a variation of it) and see what happens!

I would set the 2nd line of answer to:
idcs = strfind(mydir,filesep);
in case running code on Windows. Very useful method, incorporating it into my code right now.

An alternative solution, as pointed out by Stephen in the comments, is to use fileparts with cd (or pwd) to get the directory above the current. It might be useful depending on the context, as it was for me (R2016a) and seems to be for Cecilia, so here it is.
parentDirectory = fileparts(cd); % also works with pwd instead of cd
If you intend to use the saved string in a different platform, make sure the path delimiters are consistent with the platform. Specifically, you will have trouble from Windows to Unix or Mac systems because on Windows fileparts adopts backslashes by default. The other way around is fine because on Windows you can use either forward (/) or back (\) slashes as path delimiters, according to the fileparts documentation.

The simple, efficient, robust solution is to just use '..' to refer to the parent directory.
"If you intend to use the saved string in a different platform..."
.. .then you can trivially avoid all of that worrying and messing about with path delimiters by using '.' to refer to the current directory, and '..' to its parent. This will work correctly for MATLAB R2016a (and every other version of MATLAB too) on any platform:
fullfile('.','..',nameofmyfile)

Try using the following function
syntax:
newDir = getParentDir(dir, numUpDirs);
