How can I create following matrix using code (as I have to create a large matrix of similar nature):
A_1= [1 1 1; 0 0 0; 0 0 0]
A_2= [0 0 0; 1 1 1; 0 0 0]
A_3=[0 0 0; 0 0 0; 1 1 1]
For A_1 the first row is 1 and rest are zero. For A_2 second row is 1 and other are 0. For A_3 third row is 1 and rest 0.

try :
N=3;
A1=[ones(1,N);zeros(2,N)];
A2=[zeros(1,N);ones(1,N);zeros(1,N)];
A3=[zeros(2,N);ones(1,N)];
