def local_min_max_funct_1d(function: Sequence[Union[float, int]], mode: str, interpolation: str) -> Tuple[Sequence[float], Sequence[float]]
描述
local_min_max_funct_1dlocal_min_max_funct_1dLocalMinMaxFunct1dLocalMinMaxFunct1dLocalMinMaxFunct1dlocal_min_max_funct_1d searches for the local minima
MinMinMinMinminmin and maxima MaxMaxMaxMaxmaxmax of the function
FunctionFunctionFunctionFunctionfunctionfunction。
Since the function values are only known at discrete sampling
points, the function can interpolated by parabolas between these
points. Setting the parameter InterpolationInterpolationInterpolationInterpolationinterpolationinterpolation to
'true'"true""true""true""true""true", enables this feature. If InterpolationInterpolationInterpolationInterpolationinterpolationinterpolation is
'false'"false""false""false""false""false", extrema are always sampling points.
If ModeModeModeModemodemode is set to 'strict_min_max'"strict_min_max""strict_min_max""strict_min_max""strict_min_max""strict_min_max", extrema are
only calculated close to points with a function value that is
strictly smaller or strictly greater than the values of its direct
neighbors.
If ModeModeModeModemodemode is set to 'plateaus_center'"plateaus_center""plateaus_center""plateaus_center""plateaus_center""plateaus_center", areas with a
function value that is constant throughout several sampling points
are also considered. If such an area is identified as being a flat
extremum, its center coordinate is returned.
