# cubicLaneBoundary

Cubic lane boundary model

## Description

The `cubicLaneBoundary`

object contains information about a cubic
lane boundary model.

## Creation

To generate cubic lane boundary models that fit a set of boundary points and an
approximate width, use the `findCubicLaneBoundaries`

function. If you already know your cubic
parameters, create lane boundary models by using the `cubicLaneBoundary`

function (described here).

### Description

creates an array of cubic lane boundary models from an array of `boundaries`

= cubicLaneBoundary(`cubicParameters`

)```
[A B C
D]
```

parameters for the cubic equation *y* =
*Ax*^{3} +
*Bx*^{2} + *Cx* +
*D*. Points within the lane boundary models are in world
coordinates.
