cell array for loop assignment

Here is some code

A1 is a 1*4cell array, I want got a 2*4 cell array, but non of those statement can do,

all I got is nesting cell array

anyone any idear?

A2={};
A1={rand(10,2),rand(10,2),rand(10,2),rand(10,2);}
for i=1:4
    A2={A2;mat2cell(A{i},[5,5],2)};
    A3{i}=mat2cell(A{i},[5,5],2);
    A4{:,i}=mat2cell(A{i},[5,5],2);
    A5{1,i}=mat2cell(A{i},[5,5],2);
end

A2={};
 A={rand(10,2),rand(10,2),rand(10,2),rand(10,2),};
 for i=1:4
    A2={A2;mat2cell(A{i},[5,5])};
    A3{i}=mat2cell(A{i},[5,5]);
    A4{:,i}=mat2cell(A{i},[5,5]);
    A5{1,i}=mat2cell(A{i},[5,5]);
 end

As per my understanding, you are having a 1*4 cell array from which you want to get 2*4 cell array

You can do this by the following sample code :

Here is a sample code :

A2=cell(2,4); 
A={rand(10,2),rand(10,2),rand(10,2),rand(10,2);} 
for i=1:4 
    A2{1,i}=A{i}; 
    A2{2,i}=[5,5]; % fill the data of your interest in new column 
end 

You can refer to the following documentation for more details .

A = {rand(10,2),rand(10,2),rand(10,2),rand(10,2)}

A = 1×4 cell array
    {10×2 double}    {10×2 double}    {10×2 double}    {10×2 double}

nA = numel(A);
result = cell(2,nA);
for ii = 1:nA
    result(:,ii) = {A{ii}(1:end/2,:); A{ii}(end/2+1:end,:)};
end

disp(result);

    {5×2 double}    {5×2 double}    {5×2 double}    {5×2 double}
    {5×2 double}    {5×2 double}    {5×2 double}    {5×2 double}

An approach without loops -

A = {rand(10,2),rand(10,2),rand(10,2),rand(10,2)}

A = 1×4 cell array
    {10×2 double}    {10×2 double}    {10×2 double}    {10×2 double}

B = horzcat(A{:})

B = 10×8

C = mat2cell(B, [5 5], [2 2 2 2])

C = 2×4 cell array
    {5×2 double}    {5×2 double}    {5×2 double}    {5×2 double}
