Hi @Dyuman Joshi! I've updated my question with file and final result!

@Alberto Acri: note that storing scalar strings in cell arrays is very inefficient, and it avoids all of the benefits of using string arrays. You should be using string arrays, just as the documentation recommends:

As you want the final result to be a 4x1 cell array -

mat1 = load('value1.mat');
value1 = mat1.value1;
mat2 = load('value2.mat');
value2 = mat2.value2;
out1 = vertcat({value1},value2)
out1 = 4×1 cell array
    {1×6 cell}
    {1×6 cell}
    {1×6 cell}
    {1×6 cell}

In case you want to store them as 4x6 as well -

out2 = vertcat(value1,vertcat(value2{:}))
out2 = 4×6 cell array
    {["54"]}    {["55"]}    {["56"]}    {["57"]}    {["58"]}    {["59"]}
    {["60"]}    {["61"]}    {["62"]}    {["63"]}    {["64"]}    {["65"]}
    {["66"]}    {["67"]}    {["68"]}    {["69"]}    {["70"]}    {["71"]}
    {["72"]}    {["73"]}    {["74"]}    {["75"]}    {["76"]}    {["77"]}

Dynamically naming variables is not recommended - Why Variables Should Not Be Named Dynamically.

Store the data in an array and use indexing to access the data -

mat1 = load('value1.mat');
value1 = mat1.value1;
mat2 = load('value2.mat');
value2 = mat2.value2;
out1 = vertcat({value1},value2)
out1 = 4×1 cell array
    {1×6 cell}
    {1×6 cell}
    {1×6 cell}
    {1×6 cell}
variable = vertcat(out1{:})
variable = 4×6 cell array
    {["54"]}    {["55"]}    {["56"]}    {["57"]}    {["58"]}    {["59"]}
    {["60"]}    {["61"]}    {["62"]}    {["63"]}    {["64"]}    {["65"]}
    {["66"]}    {["67"]}    {["68"]}    {["69"]}    {["70"]}    {["71"]}
    {["72"]}    {["73"]}    {["74"]}    {["75"]}    {["76"]}    {["77"]}
