I'm just starting out in MATLAB and doing some homework for a class. What I'm trying to do is select the top-right and bottom-left quadrants of a 6x6 identity matrix and turn those smaller quadrants into identity matrices of themselves without inputting the elements individually. This is the best I could come up with, but clearly the quadrants I'm trying to select just turn into ones instead of identity matrices.
>> A=eye(6,6)
A =
1 0 0 0 0 0
0 1 0 0 0 0
0 0 1 0 0 0
0 0 0 1 0 0
0 0 0 0 1 0
0 0 0 0 0 1
>> A(1:3,4:6)=eye; A(4:6,1:3)=eye
A =
1 0 0 1 1 1
0 1 0 1 1 1
0 0 1 1 1 1
1 1 1 1 0 0
1 1 1 0 1 0
1 1 1 0 0 1
any help would be greatly appreciated!
