How can I save the data from my function as a new .mat file?

This is my code snippet:

[filepath, name, ext] = fileparts(filename);
newFilename = fullfile(filepath, name , '_RT.mat');
disp(newFilename)

save(newFilename, 'AudioRT', 'VisualRT', 'SOA')

This is the result:

/MATLAB Drive/CHECK/Participant/_RT.mat
Error using save
Cannot create '_RT.mat' because '/MATLAB Drive/CHECK/Participant' does not exist.

Error in CongruentRT (line 42)
save(newFilename, 'AudioRT', 'VisualRT', 'SOA')

But I expect this:

/MATLAB Drive/CHECK/Participant_RT.mat     % "/" need not be there

Then, I assume my files would get saved and it won't throw this error.

Change

newFilename = fullfile(filepath, name , '_RT.mat');

to

newFilename = fullfile(filepath, [name,'_RT.mat']);
%                                ^              ^

 "/MATLAB Drive/CHECK/Participant"    "/MATLAB Drive/CHECK/_RT.mat"

Error using save
Argument must be a text scalar.

Error in CongruentRT (line 43)
save(newFilename, 'AudioRT', 'VisualRT', 'SOA')
% It got split into two addresses as that became an array

Aaah, you are actually using strings. It helps when you provide this kind of important information.

Try STRCAT:

newFilename = fullfile(filepath, strcat(name,'_RT.mat'))
%                                ^^^^^^^              ^

Well, first line of my code snippet shows that. Thanks for your help. I have tested your solution and this works too so I will accept the answer.

Merry answering! :)

I found another solution meanwhile and it seems to work now.

newFilename = sprintf('%s/%s_RT.mat', filepath, name);
