How to modify a function to make it accept an array of arrays or a cell of arrays?

Hi All,

I found the attached file on internet, this file is a function that gives all the combinations of all elements of the given arrays.

ex1:

>> allcomb([1 2],[3 4])

ans =

     1     3
     1     4
     2     3
     2     4

Now, my question is how we can change on this function to make is accept a cell of arrays or an array of arrays.

ex2:

if we have the following code:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

clc

clear all

close all

for i=1:2

        p{i}=[2^i-1 2^(i)];

end

allcomb(p)%This line does not work.

Cell={};

for i =1:max(size(p))

    Cell{i}=p{i};

end

allcomb(Cell)%This line does not work.

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The lines that have the comment "%This line does not work." do not give the same answer as ex1.

Could you help me please?.

If I told you I'm not sure you'd take my advice. I gave you several pieces of advice how to improve this bad code in your other question but I can see you didn't take that advice because you're still using the same code here.

Sorry, but I think you are talking about someone else, this is the first time I post this code here.

This is the correct answer: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%

clc

clear all

close all

for i=1:2

        p{i}=[2^i-1 2^(i)];
end

Cell={};

for i =1:max(size(p))

    Cell{i}=p{i};
end

allcomb(Cell{:})

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

The output:

ans =

     1     3
     1     4
     2     3
     2     4
