count the # of rows of CSV files in a folder

I have a bunch of CSV files in a folder. I understand that I can use

https://www.mathworks.com/matlabcentral/answers/492801-how-do-i-count-the-number-of-rows-in-a-csv-file

to count a number of rows of each file. Then how can one write a loop to read all csv files in a folder to calculate the sum of rows of CSV fiels in a folder?

your_folder = 'C:\path\to\folder';

files = dir(fullfile(your_folder,'*.csv'));
fullFileNames = fullfile(your_folder,{files.name});
numRowsTotal = 0;
for ii = 1:numel(files)
    datatable = readtable(fullFileNames{ii}, 'ReadVariableNames', false);  %or true if there is a header
    numRowsTotal = numRowsTotal + height(datatable);
end
