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
