From this matrix pattern, how to create a matrix iterations automatically? Thanks guys

A =

    -3     1     0     0     0
     1    -3     1     0     0
     0     1    -3     1     0
     0     0     1    -3     1
     0     0     0     1    -3

V = [-3 1 0 0 0] 
M = toeplitz(V,V)

Hi Jos, thanks for your answer.

My desired matrix not only 5x5 (can be 10x10 , 20x20 , or more ) . But the pattern diagonal matrix such that I made ( 5x5 ) . How to make coding iteration ?

[Jos (10584)]

N = 10 ; % or 5, or 20, but => 2
V = [-3 1 zeros(1,N-2)] ;
toeplitz(V)

It's work. Thank you Jos.
