Description: Smoothing signals and computing their derivatives is a
        common requirement in signal processing workflows.
        Savitzky-Golay filters are a established method able to do both
        (Savitzky and Golay, 1964 <doi:10.1021/ac60214a047>). This
        package implements one dimensional Savitzky-Golay filters that
        can be applied to vectors and matrices (either row-wise or
        column-wise). Vectorization and memory allocations have been
        profiled to reduce computational fingerprint. Short filter
        lengths are implemented in the direct space, while longer
        filters are implemented in frequency space, using a Fast
        Fourier Transform (FFT).
