Interpolation between parametric representation and arc length
pp = pdearcl(p,xy,s,s0,s1)
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.
