I am not certain what you want, however one option would be a cell array —

v1 = rand(3)
v1 = 3×3
    0.5133    0.6163    0.4846
    0.3344    0.3004    0.8163
    0.8754    0.6556    0.6720
v2 = 'This is Variable #2'
v2 = 'This is Variable #2'
v3 = exp(v1)
v3 = 3×3
    1.6708    1.8521    1.6235
    1.3971    1.3504    2.2622
    2.3999    1.9263    1.9581
V = {v1, v2, v3}
V = 1×3 cell array
    {3×3 double}    {'This is Variable #2'}    {3×3 double}

.

Essentially, you just need to learn MATLAB. Read the various tutorials you can find. In there you would learn about the various variable classes available.

There are structs.

A.num = 1:5;
A.str = "The quick brown fox";
A.mat = rand(2);
A
A = struct with fields:
    num: [1 2 3 4 5]
    str: "The quick brown fox"
    mat: [2×2 double]

There re cell arrays.

B = cell(1,3);
B{1} = 1:5;
B{2} = "The quick brown fox";
B{3} = rand(2);
B
B = 1×3 cell array
    {[1 2 3 4 5]}    {["The quick brown fox"]}    {2×2 double}

There are simple arrays.

C = zeros(3,3);
C(1,:) = ones(1,3);
C(2,:) = 1:3;
C(3,:) = rand(1,3);
    
C
C = 3×3
    1.0000    1.0000    1.0000
    1.0000    2.0000    3.0000
    0.4258    0.5060    0.8791
