Hi ,
I want to generate a text file for the chosen csv file by extracting some values from the specific index and not to read the whole csv.
Please let me know
Thanks in advance :)

% [UNTESTED CODE!]
function Value = GetCSVElement(File, R, C)
% INPUT: File: File name
% R: Row index of wanted element. 1 row for the header assumed.
% C: Column index of wanted element
[fid, msg] = fopen(File, 'r');
assert(fid > 0, msg);
for k = 1:R + 1
s = fgetl(fid);
end
fclose(fid);
if isequal(s, -1)
error('File %s has less than %d rows.', File, R);
end
V = strsplit(s, ',');
if numel(V) < C
error('Row %d of file %s has less than %d columns.', R + 1, File, C);
end
Value = sscanf(V{C}, '%g');
end
