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.

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:

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)
