Spline curve by uniform subdivision
spcrv(c,k) provides a dense sequence
f(tt) of points on the uniform B-spline curve
f of order
k with B-spline coefficients
c. Explicitly, this is the curve
spcrv(c) chooses the order
sure that at least
maxpnt points are generated.
The default value for the maximum number of sites
be generated is
The output consists of the array f(tt).
The following would show a questionable broken line and its smoothed version:
points = [0 0 1 1 0 -1 -1 0 0 ; 0 0 0 1 2 1 0 -1 -2]; plot(points(1,:),points(2,:),':') values = spcrv(points,3); hold on, plot(values(1,:),values(2,:)), hold off
