Building a code that saves the output of each loop as a vector

I am new to MATLAB, I am trying to build a code that saves the output of each loop as a vector, i.e after making 40 loops I should have 40 vectors (each vector has different length) so that I can do further analysis. Please help?

E = 215000

K = 853

n = .166666666666666666666666666667

incr = 5

peaks = 10

stress = [0 20 -160 150 -40 330 -40 170 -20 180]

if stress(2)<stress(1)

incr = - incr

end

stress12 = stress(1):incr:stress(2)

strain12 = (stress12/E) + (stress12/K).^(1/n)

conststress = stress12(end)

conststrain = strain12(end)

plot(strain12,stress12)

hold on

for j = 2:1:peaks-1

    k = j+1;

if stress(k)<stress(j)

incr = - incr;

stressjk = stress(j):incr:stress(k)

strainjk = conststrain+(((stressjk-conststress)/E)-2*((stressjk-conststress)/(2*K)).^(1/n))

conststress = stressjk(end)

conststrain = strainjk(end)

else

incr = abs(incr)

stressjk = stress(j):incr:stress(k)

strainjk = (((stressjk-conststress)/E)+2*((stressjk-conststress)/(2*K)).^(1/n))+conststrain

conststress = stressjk(end)

conststrain = strainjk(end)

end

plot(strainjk,stressjk)

hold on

end

Hi, Please post your code linewise. Right now its difficult to understand. But from what you said I gather, you want to save stresses/forces that comes out as vector in one loop. You want to carry out 40 loops and each time save that vector of forces/stress whatever. To do this, cells are very convenient..

suppose F= vector of forces.

>>force_cell= cell(1,40); % initialize a cellarray containing 40 cells.

>>for i=1:40

 force_cell{i}= F ; 
end

Now to you have all 40 vectors stored in cells. Suppose you want to call lets say 25th force vector. do this,

>>force_cell{25}

answer will show "F" vector corresponding to 25th loop.

Hope this helps.. Cheers..!

Thank you very much for your help, I did what you suggested and it looks working. I think now I can proceed doing further analysis.
