keyg=zeros(8,8);
key=[0 0 1 0 ;0 0 1 1 ;0 1 0 1; 0 1 1 1; 1 0 0 0; 1 0 1 0; 1 1 0 1; 1 0 1 1];
key1=[0 0 1 0 0 0 1 0 ;0 0 1 1 0 0 1 1 ;0 1 0 1 0 1 0 1; 0 1 1 1 0 1 1 1];
keyg(1:8,5:8)=key;
keyg(5:8,1:8)=key1;
orig_key=keyg;

Shruthi - you may need to provide some context. What are you hoping that this code will do?

I was just trying random key generation

在 MATLAB Online 中打开

If you're asking what the output is (maybe you're away from a computer with Matlab at the moment)

keyg=zeros(8,8);
key=[0 0 1 0 ;0 0 1 1 ;0 1 0 1; 0 1 1 1; 1 0 0 0; 1 0 1 0; 1 1 0 1; 1 0 1 1];
key1=[0 0 1 0 0 0 1 0 ;0 0 1 1 0 0 1 1 ;0 1 0 1 0 1 0 1; 0 1 1 1 0 1 1 1];
keyg(1:8,5:8)=key;
keyg(5:8,1:8)=key1;
orig_key=keyg
orig_key = 8×8
     0     0     0     0     0     0     1     0
     0     0     0     0     0     0     1     1
     0     0     0     0     0     1     0     1
     0     0     0     0     0     1     1     1
     0     0     1     0     0     0     1     0
     0     0     1     1     0     0     1     1
     0     1     0     1     0     1     0     1
     0     1     1     1     0     1     1     1

I ran this using the tools in the editor used to make this post. I didn' have to even use Matlab. There is also a web-accessible version of Matlab available.
