I am getting the following error for the attached code.
Error in Readfiles (line 8)
data = readmatrix(fnames{idx});
Could you please help me out.

fname is a struct, not a cell array. Change the line to
data = readmatrix(fnames(idx).name);

This code does not contain the line
data = readmatrix(fnames(idx).name);
as shown in your previous comment. In any case, N is a cell array in your case and you can acess the filenames like this
data = readmatrix(N{idx});

% List all CSV files
fnames = dir('*.csv');
% Pre-allocate output vector
ranges = zeros(numel(fnames), 1);
% Loop over file names
for idx = 1:numel(fnames)
% Read the CSV data
data = readmatrix(fnames(idx).name);
% Get the 5th column
col5 = data(:,5);
% Get the range for this file
ranges(idx) = max(col5) - min(col5);
end
% Write the result
writematrix(ranges, 'ranges.csv');
