DIRECTION_ARROWS is a MATLAB program which makes an arrow plot of a velocity direction field, using XY and UV data stored as TABLE files.
The program is mainly a preprocessor for MATLAB's quiver routine. It reads the (X,Y) coordinates of a set of points from an "XY" file, and the corresponding horizontal and vertical velocities from a "UV" file. It then makes a few settings, computes the direction field from the velocity field, calls quiver to plot the arrows, and also traces out the convex hull of the points, which is presumably the boundary of the region.
