Given the symmetric matrix
A
0 5000.5 50.5
5000.5 0 0
50.5 0 0
and the vector
B
0 _1 0
your function fun is the sum of a quadratic part
Q =: ] mp A mp ]
and a linear part
L =: B mp ]
where mp is the matrix product +/ . *
Thus
fun =: Q + L
fun 5 3 2
151022
fun 9 2 4
183652
fun 8 6 3
482466
fun 5 4 5
202541
fun 7 2 5
143547
