If all the arrays are vectors (=1D arrays in matlab) you can store them in a matrix (=2D array).
% Pre-allocate an matrix with four "vector arrays" of 6 elements each
A = zeros(4,6) ;
Here is an example to fill this array
for k=1:4
A(k,:) = (1:6) ./ k ; % just an example
end
To access a "array" (vector!) use indexing B = A(2,:) % get second row
If the vectors have different sizes, you need to look into cells and/or structs
A = {1:3 1:10 1:5} % a cell with 3 vectors
A{3} % third vector
