hellow everyone ! Suppose i have an identity matrix .
I=eye(3) which will produce
I = [1 0 0
0 1 0
0 0 1]
Now i want to insert I into a (5X5) null matrix such that my result will be
N = [0 0 0 0 0
0 0 0 0 0
0 0 1 0 0
0 0 0 1 0
0 0 0 0 1]
How could i achieve this efficiently .Thanks in advace

N = diag([0 0 1 1 1])
