Problem 43291. Tridiagonal matrix

Given vectors u and v, make a tri-diagonal symmetric matrix such that u is in the main diagonal and v is below and above diagonal

u = [1 4 5 6]
v = [3 8 2]

the result would be:

[ 1     3     0     0
  3     4     8     0
  0     8     5     2
  0     0     2     6 ]
