ProfileZeroCrossings


Header: AVL.h
Namespace: avl
Module: FoundationPro

Finds the points of a profile at which the profile intersects the x-axis.

Syntax

C++
C#
 
void avl::ProfileZeroCrossings
(
	const avl::Profile& inProfile,
	atl::Optional<const avl::Range&> inRange,
	atl::Array<float>& outZeroCrossings
)

Parameters

Name Type Default Description
Input value inProfile const Profile& Input profile
Input value inRange Optional<const Range&> NIL
Output value outZeroCrossings Array<float>& X coordinates of the locations where the profile crosses the y=0 axis

Description

The operation assumes linear interpolation between the profile values and finds precise locations at which the profile crosses the horizontal \(y = 0\) axis. For the constant profile sections of value 0 only the integer coordinates of the sampling points in the section are returned.

Examples
inProfile = {-1.0,3.0,0.0,0.0,0.0} outZeroCrossings = {0.25, 2.0, 3.0, 4.0}

Errors

Error type Description
DomainError Range exceeds the input profile in ProfileZeroCrossings.
