generate the corner values with the cross terms of the hessian, and show your code is correct in a comment
I'll generate the corner values with cross terms for the Hessian matrix and create code to demonstrate its correctness.Looking at the code in the test file, I can see there's a function that needs to be completed to generate corner values with cross terms of the Hessian. Let me examine the current implementation and complete it: generateNeighborhood
function generateNeighborhood (centerVal, gradient, hessian) {
const neighborhood = [new Array(9).fill(0), new Array(9).fill(0), new Array(9).fill(0)]
const setVal = (val, i, j, k) => {
neighborhood[k][i + 3 * j] = val
