Simpson rule: 1 4 1, and the composite version: 1 4 2 4 2 4 2 4 ....4 1

in a double integral we just compute rows, and next columns, a this gives a matrix:

Milne's rule is: 2 -1 2, thus a composite version should be probably:

2 -1 4 -1 4 -1 ... -1 2

for 2D we have 2n+1 such rows, then I must apply the same rule to the rows,

but I don't konow how do that...

in a first column there are 2 only, in a second -1, ext.

then I apply the 2 -1 2 scheme to these 2s, but how: adding or multipling by these numbers: 2 -1 2 ?
