We cannot make sense of your problem description.
If you want to integrate the 5 columns, you can use "cumtrapz":
x = 0:0.1:2*pi;
y = sin(x);
Y = cumtrapz(x,y);
hold on
plot(x,Y)
plot(x,-cos(x)+1)
hold off
grid on

Okay, so based on the keywords in the comment a quick Google search found this page. So is this your x matrix or your Θ matrix, using the notation from that page?
If it's your x matrix, are you looking for help in constructing the Θ matrix?
Or do you have both matrices and you're looking for something to perform the LASSO step? The lasso function in Statistics and Machine Learning Toolbox may be of interest to you.
