Hi there, i am a begginer in Matlab and i have problem with solving the matrix.. The problem is that i dont know how to change last row in matrix with numbers
![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/414223/image.png)
[0 0 0 -1] - matrix one
[0 0 -2 -1] - matrix two
[0 -3 -2 -1] - matrix three
[-4 - 3 -2 -1] - matrix four
And here is my code:
for n = 2:5
A22 = eye(n, n-1);
A21 = zeros(n, 1);
A = [A21, A22];
end
(this code is working, i only need to change last row)

this can work
for n = 2:6
A22 = eye(n, n-1);
A21 = zeros(n, 1);
A = [A21, A22];
end
A = A(1:5,:)

i don't know if the result is correct, but the eigenvalues can be complex.
