static void cvFitLine(

	double aeps, 
	[OutAttribute] array<float>^ line
)

Parameters

points (IntPtr): Sequence or array of 2D or 3D points with 32-bit integer or floating-point coordinates

distType (DIST_TYPE): The distance used for fitting

param (Double): Numerical parameter (C) for some types of distances, if 0 then some optimal value is chosen

reps (Double): Sufficient accuracy for radius (distance between the coordinate origin and the line), 0.01 would be a good default

aeps (Double): Sufficient accuracy for angle, 0.01 would be a good default

line (array< Single >[]()[]): The output line parameters. In case of 2d fitting it is array of 4 floats (vx, vy, x0, y0) where (vx, vy) is a normalized vector collinear to the line and (x0, y0) is some point on the line. In case of 3D fitting it is array of 6 floats (vx, vy, vz, x0, y0, z0) where (vx, vy, vz) is a normalized vector collinear to the line and (x0, y0, z0) is some point on the line.
