How to create a list?

Hi,

I want to store numbers in an object A, so that when I call A(i) I can got the i-th element.

But each A(i) may have different length and thus I can't put them in a matrix or array. A list would be preferred, and seems I can't create such an object in Matlab.

How can I proceed? Thanks.

Illustration with an example would avoid guessing.

For example, I want to store [1;3;6], [2;4] and [3] into the same object A, such that when I call A(2), I can get [2;4]. How can I do that?

MATLAB does not have a "list" data class. If you want a container class to hold other arrays, you can use a cell array, a structure, a table, etc.:

Store it as a cell array:

>> A={[1;3;6], [2;4], [3]}

A =

  1×3 cell array

    {3×1 double}    {2×1 double}    {[3]}

>> A{2}

ans =

     2
     4
