hey,
I am trying to copy multiple files (with different names) from one folder to another. however, filename is not accepting y as input because it is not an array, how to fix this?

If you are trying to copy all files inside trialfiles folder to folder named output then it is done as follows
source = fullfile('Users','macbook','Desktop','matlab','trialfiles');
destination = fullfile('Users','macbook','Desktop','matlab','ouptut');
copyfile(source,destination); % will copy all files from trialfiles folder to output folder
In your code filename should be set to a character vector of file name like 'trial.xlsx', basically fullfile constructs the filepath by receiving parts of file path as names and then adds the seperators '/' or '\' according to OS.
More information on fullfile and copyfile can be found in the following documentation
I hope this answers your queries, please accept the answer if it does
Thank you

I understand that you are trying to copy a file from one directory to another using matlab.This can be achieved as follows:
Since you are trying to copy a file ,you have to provide the filename instead of loading the data and trying to save it.
clc
y = readtable('trial.xlsx');
p1 = '/Users/macbook/Desktop/matlab/trialfiles';
pdest = '/Users/macbook/Desktop/matlab/output';
filename = 'trail.xlsx' %%% filename variable should have filename instead of data loaded from file.
source = fullfile(p1,filename);
destination = fullfile(pdest,filename);
copyfile(source,destination);
I hope this resolves your query.
Thanks,

Since the vector of filename is not supported in the fullfile function you can try the below iterative approach
%assuming that all the filenames are in first column of the excel sheet.
clc
y = readtable('trial.xlsx');
p1 = '/Users/macbook/Desktop/matlab/trialfiles';
pdest = '/Users/macbook/Desktop/matlab/output';
data=y{:,1};
%Iterating over each file name.
for i=data
filename = i
source = fullfile(p1,filename);
destination = fullfile(pdest,filename);
copyfile(source,destination);
end
%Hope this resolves the issue

There are a couple of points which were not consistent. Here is the corrected code.
clc
SourceF = 'trial.csv';
y = readtable(SourceF);
p1 = 'C:\Users\17018\Documents\MATLAB';
pdest = 'C:\Users\17018\Documents';
filename = 'trial_COPY.csv';
source = fullfile(p1,SourceF);
destination = fullfile(pdest,filename);
copyfile(source,destination);
