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
