Try this —

M = hankel(1:4,4:-1:1)
M = 4×4
     1     2     3     4
     2     3     4     3
     3     4     3     2
     4     3     2     1

This is one way:

A = flipud(toeplitz([4 3 2 1]))
A = 4×4
     1     2     3     4
     2     3     4     3
     3     4     3     2
     4     3     2     1
