Remove the 1x1 Cell Array from the Cell Array

Hey everyone,

I have the following code:

s{1} = [4 2];

s{2} = [2 1];

S{1} = [s{1}];

m = 1;

m = 1

for j = 1:m

Temp_D{j} = S{j} - s{j+1};

end

Temp_D = cell2sym(Temp_D);

D{1} = Temp_D;

D{1}

ans =

However, when I use this chunk of code as a function in my code, I get the following result :

Why do I need to do D{1}{1} To access the the array [2, 1], can I solve this problem?

Why do you consider this as a "problem". It is exactly, what the code instructs Matlab to do. What do you want instead?

Ahmed Radhi 2022-9-27

Because I want the output to be D{1} = [2, 1], instead.

In this way, let’s assume I added one more array to D, such that D{2} = [1, 2, 0], how can I access it? Is it by D{2}{1}?

If you want D{1} = [2, 1], use:

D{1} = [2, 1]
D = 1×1 cell array
    {[2 1]}
% or equivalently
D = {[2, 1]}
D = 1×1 cell array
    {[2 1]}

Expanded:

D = {[2,1], [1,2,0]}
D = 1×2 cell array
    {[2 1]}    {[1 2 0]}
D{1}
ans = 1×2
     2     1
D{2}
ans = 1×3
     1     2     0

Maybe in your case:

D = Temp_D;
% not D{1} = ...

What is the purpose of cell2sym?

Okay. Do you really want a symbolic array?

Ahmed Radhi 2022-9-27

I used the cell2sym to put all the arrays in Temp_D in one array, and then I can put it as a single array in the first cell of D. So yes I want a symbolic array.
