% [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
