suppose, I have 3 variables containg some data but I want to store all the datas of the 3 separate variables in a single variable.

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
