Colored 2D Vector Field Plotter

Plots 2D vectors colored according to their lengths.

COLORVFIELD Colored 2D Vector Field Plotter.

COLORVFIELD(X,Y,U,V) plots colored vectors with components (u,v) at the points (x,y). The vectors are colored using the jet color map (with the smallest vectors colored blue the largest colored red) and are divided into 32 discrete color levels.

COLORVFIELD(X,Y,U,V,NUMBER_COLOR_LEVELS) divides the color map into NUMBER_COLOR_LEVELS dicrete color levels.

Example:
X = linspace(-10,10,32);
Y = linspace(0, 0, 32);
U = linspace(-1,-5,32);
V=linspace(1,5,32);
colorvfield(X,Y,U,V,16); % plot 16 color levels
