csvFile = dir("*.csv") ;
N = length(csvFile) ;
for i = 1:N
data = readtable(csvFile(i).name) ;
iwant = data.Points_0;
iwant1 = data.Points_1;
% do what you want
end

csvFiles = dir("*.csv") ;
N = length(csvFiles) ;
for i = 1:N
data = csvread(csvFiles(i).name) ; % also read about xlsread
iwant = data(:,1:2) ; % read first two columns
% do what you want
end
