How to create this matrix shown in the screenshot?

Answer 1

[Prakash S R]

toeplitz() is your friend!

toeplitz([4 0 -2 0 0 0])

How would I do the same for a 32x32 matrix?

[Prakash S R]

The argument to toeplitz() is the first row of the desired matrix (in your case a 1x32 vector).

[Torsten]

Logically, it should be

toeplitz([4, 0, -2, zeros(1,29)])

shouldn't it ?
