1D savgol test

[nghorbani]

Hi, I wrote a simple test and the output size is different ` input_arr = np.random.rand(10,1) output_arr = filter1D(input_arr.reshape(-1), mu=5, poly=3, order=0)

output_arr2 = savgol_filter(input_arr, 5, 3, axis=0, mode='wrap')

` resulting in output_arr of shape 10, and output_arr2 shape of 5. it has to do with conv(...,'full'). if "same" is used the dimension are correct but still the values are different

wierd is that they sometimes (at certain input values) come very close

the 3D filter looks meaningful

input_arr = np.random.rand(10,1,3) # (100,1,3) print(f"Input array: {input_arr.shape}") output_arr = filter3D(input_arr, mu=7, poly=5, order=0) # (100,1,3) plot_3d(input_arr, output_arr)
