How to save a file with name saved in a variable ?

I need to save the output of my script in a .mat file which have as name the name I extract from the cell of an excel file.

The way I get the name is this:

[filename, filepath, ~] = uigetfile('*.xlsx');
[~,nnn] = xlsread([filepath, filename], i, 'A:A');  %import subject name
Name=[nnn(2,:)];

So the name is saved inside variable 'Name', and it changes every time inside the loop ( every time it takes it from a different excel work page).

filename=Name
save (filename , 'variables') doesn't work

and

filename=sprintf('%s',[Name{:}]) gives the error of 'cell' input.

How can I solve this?

Doesn't work how? What's the error message?

You must use

filename=Name{1} ;

And also give a proper extension...
