# closestProjections

Find orthogonal projections between path tangent vector and query point

*Since R2022a*

## Syntax

## Description

`[`

attempts to project each `arclengths`

,`distances`

] = closestProjections(`refPath`

,`points`

)*xy* point in the *points*
matrix, onto each clothoid segment contained in the reference path,
`refPath`

, such that the projection vector is orthogonal to the path
tangent-angle. Returns closest orthogonal projection between the curve and query point in
each segment as a pair of two cell arrays, `arclengths`

and
`distances`

containing the arclengths and distances
respectively.

`[___,`

optionally returns the projected points, `projPoints`

] = closestProjections(`refPath`

,`points`

)`projPoints`

as a cell array
containing path data evaluated at the corresponding arclengths element.
