Hello,

I am having problems with the limit of RAM memory. In my application, I have a loop like the following:

%% 1. Data obtaining
n_loops=1000;
all_results = zeros(dim1, dim2, n_loops)
for i=1:n_loops
    %result_of_one_loop = get_result_command;
    all_results(:,:,i) = result_of_one_loop;
end
%% 2. Post-processing
        %Post-procesing code here.

This code runs out the RAM. Is there any option to solve this problem? Maybe saving into the disk memory the results file, increasing the size in each loop (but not overwriting)? Thank you so much for your help.

This piece of code is too simplified, to explain the source of the problem. If the pre-allocation zeros(dim1, dim2, n_loops) is working successfully, filling the memory is no reason for further allocations.

Please postr some code, which reproduces the problm and pos a copy opf the complete error message. This will show us, which line is failing.
