You can save them into a cell array. Read about cell.

% Dummy data demo
A = cell(2,3) ;
for i = 1:2
    for j = 1:3
        A{i,j} = rand(1,3) ; 
    end
end
A

A = 2×3 cell array
    {[0.4545 0.5859 0.6816]}    {[0.4719 0.1491 0.4351]}    {[0.6638 0.1821 0.8371]}
    {[0.0395 0.8344 0.9757]}    {[0.2598 0.7795 0.2263]}    {[0.8550 0.8271 0.8162]}

You can access the cell array using: A{1,1}, A{2,3} etc.

You can print the specific cell array element using:

A{1,1}(1)

ans = 0.4545

A{2,2}(3)

ans = 0.2263

You can chnge any value in the cell array using:

A{1,1} = [1 2 3] ; % changing entire cell array (1,1)
A{2,2}(3) = 0 ;  % changing third element of cell array (2,2)
