pdearcl

Interpolation between parametric representation and arc length

Syntax

-     pp=pdearcl(p,xy,s,s0,s1)

Description

`pp=pdearcl(p,xy,s,s0,s1)` returns parameter values for a parameterized curve corresponding to a given set of arc length values.

`p` is a monotone row vector of parameter values and `xy` is a matrix with two rows giving the corresponding points on the curve.

The first point of the curve is given the arc length value `s0` and the last point the value `s1`.

On return, pp contains parameter values corresponding to the arc length values specified in `s`.

The arc length values `s`, `s0`, and `s1` can be an affine transformation of the arc length.

Examples

See the example `cardg` on the reference page for `pdegeom`.
