C#
 
void fil::QuadraticRegression_RANSAC
(
	const ftl::Array<float>& inYValues,
	ftl::Optional<const ftl::Array<float>& > inXValues,
	ftl::Optional<int> inMaxOutlierCount,
	float inMaxInlierDistance,
	ftl::Optional<int> inIterationCount,
	fil::QuadraticFunction& outQuadraticFunction,
	ftl::Array<float>& outEstimatedValues,

)

Parameters

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