getcurve - Interactive creation of cubic spline curve
Syntax
[xy,spcv] = getcurve
Description
[xy,spcv] = getcurve
displays a gridded window and asks you for input. As you click on
points in the gridded window, the broken line connecting these points
is displayed. To indicate that you are done, click outside the gridded
window. Then a cubic spline curve, spcv, through
the point sequence, xy, is computed (via cscvn) and drawn. The point sequence and, optionally,
the spline curve are output.
If you want a closed curve, place the last point close to
the initial point.
If you would like the curve to have a corner at some point,
click on that point twice (or more times) in succession.
