How to multiply two cell array

Dear friend,

How to achieve the goal of multiply two cell array using MATLAB like this?

A={1,2,3},B={'a','b','c'}

to achieve A*B={{1,'a'},{1,'b'},{1,'c'},{2,'a'},{2,'b'},{2,'c'},{3,'a'},{3,'b'},{3,'c'},}

Your help would be highly appreciated!

Hi,

C = {};
A={1,2,3};
B={'a','b','c'};
for i = 1:length(A)
    for j = 1:length(B)
        C{end+1} = {A{i},B{j}};
    end
end

Dear Florian,

how to display the cell array like this {{1,'a'},{1,'b'},{1,'c'},{2,'a'},{2,'b'},{2,'c'},{3,'a'},{3,'b'},{3,'c'},}

I use celldisp, but it shows like this:

Thank you!

celldisp(C)

C{1}{1} =

1

C{1}{2} =

a

C{2}{1} =

If you type disp(C) you will get :

>> disp(C)
  Columns 1 through 7

    {1×2 cell}    {1×2 cell}    {1×2 cell}    {1×2 cell}    {1×2 cell}    {1×2 cell}    {1×2 cell}

  Columns 8 through 9

    {1×2 cell}    {1×2 cell}
    

if you type

>> for i = 1:length(C)
disp(C{i})
end
    {[1]}    {'a'}

    {[1]}    {'b'}

    {[1]}    {'c'}

    {[2]}    {'a'}

    {[2]}    {'b'}

    {[2]}    {'c'}

    {[3]}    {'a'}

    {[3]}    {'b'}

    {[3]}    {'c'}
    
    

You can also type :

>> disp([C{1,1:end}])
  Columns 1 through 12

    {[1]}    {'a'}    {[1]}    {'b'}    {[1]}    {'c'}    {[2]}    {'a'}    {[2]}    {'b'}    {[2]}    {'c'}

  Columns 13 through 18

    {[3]}    {'a'}    {[3]}    {'b'}    {[3]}    {'c'}

Thank you for the elaborate explanation!
