Trait Implementations

impl KernelGenerator for SavitzkyGolay1DerivOrder34

fn required_number_of_points(&self) -> usize

The total number of points required for this kernel. Cannot be zero - usually an odd value.

fn get_kernel_value(&self, offset: f64) -> f64

Calculates the value for the convolution kernel at the specified offset. The range of valid offsets is [-offset_size, 0, offset_size]

fn expected_weighted_sum(&self) -> f64

Returns the expected value of the kernel. Most kernels will be 1.0 though some (like first-derivative kernels) will be at zero.

fn absolute_value_offset(&self) -> usize

The minimum (negative) and maximum (positive) index into the [get_kernel_value] function. This defaults to [(1-N)/2, (N-1)/2].
