MATLAB: Read multiple .CSV files with csvread using a loop

csvloop

Dear All,
I hope that you may help me,
Say I have n files named "droplet.n.csv" where n goes from 0 to 100 ( I am attaching five .csv files)
Each file has two rows. I want to extract the second row of each file and save it in another file. So what I would end up having on MATLAB is a matrix with many rows as n there are (in this case 100)
Thanks in advance

V = 0:4;
N = numel(V);
C = cell(1,N);
for k = 1:N
    F = sprintf('droplet.%d.csv',V(k));
    C{k} = readmatrix(F,'NumHeaderLines',1);
end
M = vertcat(C{:})
M = 5×14
         0         0         0   -0.0000   -0.0000   -0.0000    0.0000    0.0708         0         0         0    0.0130    0.0115    0.0117

Or use readtable to get a table at the end, which might be more convenient to use.
