help for matrix manipulation with loop

%for n=i (i is variable, taken 6 this example), I need to create the below matrix % i numbers rows and (i-3) numbers columns need to be created as follow;

j=[0;0;0;1;0;0]
m=[0;0;0;0;1;0]
k=[0;0;0;0;0;1]

created_matrix=[j,m,k]

%I need to write a loop w.r.t. the i variable for creating this matrix.

Using vectorized code is much neater, faster and more robust than using loops. Learn to write vectorized code and suddenly MATLAB becomes a powerful tool for you to use...

Answer 1

[Azzi Abdelmalek]

[zeros(3);eye(3)]

Answer 2

[Andrei Bobrov]

n= 3;

out = [zeros(n);eye(n)];

with loop

out = zeros(2*n,n);
for jj = 1:n
    out(jj+3,jj) = 1;
end
