Random number of nested for loops

Dear all,

I have the following problem: I want to input an integer number 'N', then inside the program I need to generate automatically 'N' nested for loops. For example:

*If I put N=2, I need the program by itself to make the following:

for i=0:1

    for j=0:1

     ...

    end

end

*If I put N=3, I need the program by itself to make the following:

for i=0:1

    for j=0:1

        for j=0:1

        ...

        end

    end

end

and so on.

Thank you in advance.

Hadi.

Hadi, maybe there's better ways to go about solving your problem. What exactly do you need your loops to do?

[hadi]

Thank you Mischa for your reply, actually I have random integer number (N) of variables that takes the values 0 or 1, so I want to generate all the combinations of these variables.

Hi Hadi.

Check nchoosek function. Maybe works for you.

Sorry Mischa, but it seems not working.

in more details what I need, if N=2, I want the following output:

00

01

10

11

if N=3:

000

001

010

011

100

101

110

111

and so on....and that is not working with nchoosek function.

Hadi, without any further requirements on output data type, etc., how about

 myarray = dec2bin([0:2^N-1],N-1)

Thank you so much Mischa, wish you a nice weekend.
