really appreciate help.

thanks

that should it

% open file fh = fopen('test.txt');  % read data (adjust 10000 if necessary) dat = textscan(fh, '%d %s %d %d %s', 10000);  % extract high , low values hi = dat{4}; lo = dat{3};  % create grid [ hig, log ] = meshgrid(hi, lo');  % compare high, low overs = ~(log >= hig);  % check both ends & 0 out diagonal res = overs & overs' & ~logical(eye(length(hi)));  % close file fclose(fh);  res
