filename = '270219etc.CSV';
S = fileread(filename);
NLpos = find(S == sprintf('\n'));;
S(1:NLpos(10)) = []; %delete first 10 lines
S(S==',') = '.';
fmt = repmat('%f', 1, 8);
data = cell2mat( textscan(S, fmt, 'Delimiter', ';'));

Hello Walter, could please explain me what does the line 3 in the code NLpos does? Thank you

NLpos is the position of all of the newlines in the input file. Indexing at 10 gives you the position of the end of the 10th line of input. You then remove everything from the beginning to there which removes the first 10 lines from the string.
