cquiver

Color quiver based on magnitude or angle. Also, support uniform sampling by averaging or taking the fastest velocity within each grid cell.

cquiver(x, y, u, v) plots quiver for at given points (x, y) with the velocity (u, v)

quiv = cquiver(x, y, u, v) returns quiver structure with two properties,
Head and Tail. Here, Head and Tail are the patches which are used for drawing heads and tails.

quiv = cquiver(x, y, u, v, 'cdata', 'angle') set color based on angle.
quiv = cquiver(x, y, u, v, 'sampling', h) plots quiver plot
at uniform grid where grid size is h.
Default sampling method is average.
Sampling method can be changed to 'fastest' by using
quiv = cquiver(x, y, u, v, 'sampling', h, 'samplingmethod', 'fastest')
In this case, the fastest one will be chosen from the rectangle
(X(i)-h/2, X(i)+h/2) x (Y(i)-h/2, Y(i)+h/2).
