Syntax

C++
C#
 
void avl::QuadraticRegression_RANSAC
(
	const atl::Array<float>& inYValues,
	atl::Optional<const atl::Array<float>& > inXValues,
	atl::Optional<int> inMaxOutlierCount,
	float inMaxInlierDistance,
	atl::Optional<int> inIterationCount,
	avl::QuadraticFunction& outQuadraticFunction,
	atl::Array<float>& outEstimatedValues,
	atl::Array<float>& outResiduals
)

Parameters

Name Type Range Default Description
inYValues const Array<float>& Sequence of ordinates
inXValues Optional<const Array<float>& > NIL Sequence of abscissae, or {0, 1, 2, ...} by default
inMaxOutlierCount Optional<int> 0 - NIL Determines how many outlier points can be present to end the search
inMaxInlierDistance float 0.0 - Distance from a parabola for point to be considered an inlier
inIterationCount Optional<int> 1 - NIL Number of iterations; Auto means that all point triples will be used
outQuadraticFunction QuadraticFunction& Quadratic function approximating the given point set
outEstimatedValues Array<float>& The result of application of the computed function to the X values
outResiduals Array<float>& Difference between an input Y value and the corresponding estimated value
