Store values from loop

Hi Matlab,
I'm running a program, calculating the recurvie residuals (see code below). The loop indicates the model is run for some base period (Z) until end of the sample.
for (i = Z:206)
%data
vX = [LOG_GDP(1:i,:,1), gvm_GDP(1:i,:,1), goverment_bond(1:i,:,1), t_bill(1:i,:,1), inflation(1:i,:,1), LOG_private_investment(1:i,:,1), LOG_mon_base(1:i,:,1), LOG_gvm_spending(1:i,:,1), excess_return(1:i,:,1), Unemployment(1:i,:,1), LOG_private_con(1:i,:,1), LOG_house(1:i,:,1)];
%function to calculate residuals from VECM
[res1] = f(vX, K, r, p)
end
However, I do not understand how to store the estimates forthe loop. If I run the program, it only returns the values for last value.
Does someone know how to store the values?
Any help is greatly appreciated
Best regards

If you want to store results from all iterations, you need to store them and not overwrite them:
res1 = cell(1,100);index = 0;
for i = Z:206
%data
vX = [LOG_GDP(1:i,:,1), gvm_GDP(1:i,:,1), goverment_bond(1:i,:,1), t_bill(1:i,:,1), inflation(1:i,:,1), LOG_private_investment(1:i,:,1), LOG_mon_base(1:i,:,1), LOG_gvm_spending(1:i,:,1), excess_return(1:i,:,1), Unemployment(1:i,:,1), LOG_private_con(1:i,:,1), LOG_house(1:i,:,1)];
%function to calculate residuals from VECM
index = index+1;
res1{index} = f(vX, K, r, p);
end
res1((index+1):end) = []; % remove unused elements

You should not use numbered variables. That encodes data in the variable name, which is a fragile method of design that doesn't scale well.
res = cell(100,4);index = 0;
for n=1:3
index = index+1;
[res{index,:}]=example_function;
end
res((index+1):end,:) = []; % remove unused elements
disp(res)
% example function with 4 outputs
function [a,b,c,d]=example_function
a=1+rand;b=2+rand;c=3+rand;d=4+rand;
end
