It accepts two arguments: `magnitude`, which scales the kernel values (default is 1), and `normalize`, which normalizes the kernel to sum to 1 (default is false). The function returns a Kernel object with the weights matrix: `[-1, 0, 1]`, `[-2, 0, 2]`, `[-1, 0, 1]`. The kernel can be used in both Javascript and Python coding environments.\n"]]
