store data from for cycle

I need to store the data in an array. I have a plot Y versus the time (tfinal =m) and the Y value is calculated n-times from a n-loop. I need to store the data in mxn array. at the moment I am able to store just 1xn vector, loosing the information on the time. The part of the m.file are the following

index=0
for i=1:Loop
   t=0; %start time 
   t_end=40; %end time
   t_sample=1; %sample interval for gathering data
   ........
   j=1; 

    t_ar(1,t_end/t_sample+1)=0; 
    t_ar(1,j)=t; 
    Y1_ar(1,t_end/t_sample+1)=0; 
    Y1_ar(1,j)=Y1; 
    etc etc
end

you should simply use two for:

    m =5; n=7;
    Mat = zeros(m,n);
    for i = 1:m
        for j = 1:n
             Mat(i,j) = i+j;% what ever
        end
     end

Hi I have use this m =Loop; n=t_end; Mat = zeros(m,n); for i = 1:m for j = 1:n Y4_array(i,j) = i+j;% what ever end end

at the end of the n-loop and if I try to visualize Y4_array(i,j) I can see Y4_array(i,j)
