MATLAB: I have to create a matrix using only zeros, ones and eye

Question

This is the matrix:

1 1 1 1 1

0 1 0 0 0

0 0 1 0 0

0 0 0 1 0

0 0 0 0 1

so far I wrote B=ones(1,5); C=eye(4,5); A=[B;C]

But this command didn't come out right. Can someone please help me.

Answer 1

your command A = [B;C] concatenated them vertically.

Try:

C = eye(5)
C(1,:) = 1; % turns every element along the first row to 1.
