Reshape Cell array dimensions

Dear Community,

I am facing a problem with a cell array dimension. After obtaining it with a for loop the dimension of it is 88x88 containing 6x6 matrix inside each variable. What I want to do is to change it to 176x176 cell array containing a 3x3 matrix as a variable. This is where I am currently stucked at:

Gesamtsystem_Kugel = cell(88,88);
for ki = 1:88
    for ji = 1:88
        if ki == ji
            Gesamtsystem_Kugel{ki,ji} = Ubertragungsmatrix_sp{ki,:};
        elseif ki == ji-1
            Gesamtsystem_Kugel{ki,ki+1} = -Einheitsmatrix;
        else
            Gesamtsystem_Kugel{ki,ji} = Matrix_0;
        end
        
    end
    
    
end

New_Gesamtsystem_Kugel = reshape(Gesamtsystem_Kugel,[],[176,176]);

But Unfortunately its not working. I'm getting "Error using reshape

Size arguments must be integer scalars."

Could you please help me?

reshape() is not able to do anything close to that. It can never repackage the data into other containers. All that reshape can do is change the numbering used to represent memory, such as re-arranging

1
2
3
4

to

1 3
2 4

What you need is something like

New_Gesamtsystem_Kugel = mat2cell(cell2mat(Gesamtsystem_Kugel), 3 * ones(1,176), 3 * ones(1,176));

It Works!! Thank you !
