CUTPOLYGON - Split a 2D polygon by a line, and remove one of the sidesUse CUTPOLYGON to cut alias intersect alias split alias slice a polygon P(being a series of connected X,Y coordinates) with a line L (defined bytwo points), removing a specified side s. L can serve as a bottom limit('B'), top...

[X,Y,Z]=polyrevolve(x,z,n)This function revolves a 2D polygon around the Z-axis. It copies the 2D data points evenly around the axis and produces a 3D data set suitable for input to MESHGRID and GRIDDATA to create a 3D surface.Useful to convert 2D axisymmetric data to 3D surfaces for presentation...
