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 parametrized 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.

See the examples in Geometry.
