This kernel's values can be scaled using the `magnitude` parameter (defaulting to 1) and normalized to sum to 1 with the `normalize` parameter (defaulting to false). The function, when invoked, returns a kernel represented by a weight matrix: `[5, -3, -3], [5, 0, -3], [5, -3, -3]`. This is demonstrated in both JavaScript and Python examples.\n"]]
