Ran in:
Since this is impossible in the most basic sense, I assume it is not homework.
Simple matrices in MATLAB cannot store a variable number of elements, or a multiple number of elements in each position.
However, it is possible. You just need to learn about the alternaitve type of arrays in MATLAB. In this case, a cell array is perfect.
A = [1; 2; 3; 4; 5];
B = [1; 2; 3; 4];
AB = {A,B}
AB = 1×2 cell array
{5×1 double} {4×1 double}
Now you can access either of those vectors simply as
AB{1}
ans = 5×1
1 2 3 4 5
AB{2}
ans = 4×1
1 2 3 4
