Constuctiing special array (like binary)
显示 更早的评论
Hi, I'am new to matlab and I want to make an nxn matrix containing as first row zeros and as last row ones. The other rows should be like binary digits.
Example with n=4:
0000
0001
0010
0011
0100
0101
0110
0111
1000
1001
1010
1011
1100
1101
1110
1111
Thank you!!

The matrix you've shown is not nxn. It is 2^n x n.

More generally
m=5; n=3;
[c{1:n}]=ndgrid(1:m);
result=reshape( cat(n+1,c{end:-1:1}),m^n,n )

Take a look at COMBN:
USe like this:
N = 2 ; M = 3 ;
combn(0:M-1,N)
